Brushless DC motors modeling with three main parts: Stator, Rotor and Hall Sensor as shown in [[#img-1|Figure 1]].  A three-phase BLDC motor has three stator phases that are excited two at a time to create a rotating electric field as represented in Figure.2. The excitation on the stator must be sequenced in a specific manner while knowing the exact position of the rotor magnets [17]

BLDC motor is modeled using transfer equations with voltage and current equations with inverter and gate decoder circuits. Motor model is based on input parameters of Van,Vbn,Vcn and load torque(Tl) as shown in equations(1-3,8) to generate voltage with corresponding back-EMF (Ea, Eb,Ec). To generate angle back-EMF a look up based logic is used with motor back-EMF constant (Ke) as described. Total electromagnetic torque is become conversant with by summing electrical and mechanical torque with product of torque constant (Kl). The mechanical side motor modeling is carried in a transfer equations based modeling as parameter rotor inertia, static and rotor dynamic torque constant. The complete modeling of BLDC motor with inverter gate drive and back-EMF generations in transfer equations is shown in [[#img-7|Figure 7]] to form transfer function and modeled using MATLAB-SIMULINK [19].

Abstract

This paper deals with mathematical modeling of Permanent magnet brushless DC (BLDC) motor in MATLAB-SIMULINK environment.

Modeling of BLDC motor carried in transfer function, transfer equations and state space model to verify the performance as actuators. Mathematical switches to control electronic commutation of BLDC motor based on signals of Hall Effect position sensor using three-phase inverter drive. Performance of the simplified mathematical inverter fed BLDC motor under steady state and dynamic conditions analyzed. Due to the switching losses during PWM generation generates low ripple content in torque of BLDC motor which described and eliminated through state space model. Comparison made of proposed modeling of BLDC motor with motor parameters like back-EMF, stator current and speed of BLDC motor, proposed work suggests the state space modeling holds a superior method for design of BLDC motor during high dynamic load performance and operating ranges.

Keywords: BLDC motor, transfer equation, MATLAB, simulink, transfer function, state space model

1. Introduction

BRUSHLESS dc motor recommended high and low power applications due to their advantages of high-efficiency, high torque/inertia ratio, variable speed operation, and low electromagnetic interference [1]. A BLDC motor is silent operation, compact form, high torque-speed characteristics reliability and low maintenance [2-3]. Stator with three-phase winding arranged in trapezoidal nature excited with permanent magnets on the rotor. BLDC motor adds advantage of brush-less in commutator arrangement and an electronic based commutation of hall based position sensors used as a feedback signals [4-5]. the limitations met in BLDC motor due for variable speed operation over last decades continuing technology development in power semiconductors, microprocessors, adjustable speed drivers control schemes and permanent-magnet brushless electric motor production joined to enable reliable, cost-effective solution for a broad range of adjustable speed applications [6-8]. However, modelling of BLDC is a challenge to any users due its stator winding in trapezoidal nature and rotor magnets position needs to be sensed at every instant to operate particular switches in ON and OFF condition [9-12]. A Hall Effect sensor is used to provide rotor magnets information and corresponding decoding signals to ON –OFF PWM signals. It is necessary to model actuator with effective dynamic performance system and less ripple harmonics [13-16].

The proposed BLDC motor modelling is carried in MATLAB simulink environment. MATLAB is an efficient tool for modelling an electrical systems and it is necessary to design BLDC motor i.e actuator for desire performance in overall systems [17-18]. Modelling of BLDC motor in MATLAB is proposed in this paper with three modelling methods state space model, state transfer equations and transfer functions. Modelling of BLDC motor is carried with three subsystems Modelling of Inverter, Modelling of Motor and Modelling of Decoder.

2. Modelling of BLDC motor

Brushless DC motors modeling with three main parts: Stator, Rotor and Hall Sensor as shown in Figure 1. A three-phase BLDC motor has three stator phases that are excited two at a time to create a rotating electric field as represented in Figure 2. The excitation on the stator must be sequenced in a specific manner while knowing the exact position of the rotor magnets [17]

where , and are the stator phase voltages, is the stator resistance per phase, , and are the stator phase currents are inductance of phases. It has been assumed that resistance of all the winding are equal. It also has been assumed that if there no change in the rotor reluctance with angle because of a no salient rotor and then

PWM Current Controller generation is dependable to generate three phase reference currents, to generate PWM Current Controller block to compare reference current and observed current. Current error generates fed to build up required PWM signals for switching power electronics switches to drive BLDC motor as shown in Figure 4 a MATLAB-SIMULINK model.

4.1 Modelling of BLDC motor in transfer function

BLDC motor parameter equation is derived in a transfer function block in a behavior to deliver desired current, back-EMF speed and torque motor characteristics. The complete MATLAB model is modeled in Figure 5 with the load torque is tested for different load applying conditions to verify the proposed modeling procedure is suitable as a motor. Back-EMF generation for three phases is simulated using corresponding theta and gamma values manipulated from motor position information as represents in Figure 6.

4.2 Modelling of BLDC motor in transfer equation

BLDC motor is modeled using transfer equations with voltage and current equations with inverter and gate decoder circuits. Motor model is based on input parameters of Van,Vbn,Vcn and load torque(Tl) as shown in equations(1-3,8) to generate voltage with corresponding back-EMF (Ea, Eb,Ec). To generate angle back-EMF a look up based logic is used with motor back-EMF constant (Ke) as described. Total electromagnetic torque is become conversant with by summing electrical and mechanical torque with product of torque constant (Kl). The mechanical side motor modeling is carried in a transfer equations based modeling as parameter rotor inertia, static and rotor dynamic torque constant. The complete modeling of BLDC motor with inverter gate drive and back-EMF generations in transfer equations is shown in Figure 7 to form transfer function and modeled using MATLAB-SIMULINK [19].

4.3 Modelling of BLDC motor in State space modelling

BLDC motor equations is modeled in state space form and fed through a state space block sets MATLAB simulink model as in Figure 8 with corresponding input voltage variables and output variables as velocity, theta angle and current. The state space model equations variables model is implemented, by considering: the stator phase resistances and inductance described as per data sheets faulhaber motor. In modeling of inverter a mathematical switches is considered neglecting the hysteresis and eddy current losses.

From the results obtained from three modeling techniques of BLDC motor in Sim-power system has better performance compared with others. Powergui block in MATLAB has automatically converted the MATLAB-model into average model in SIMULINK which is not possible in transfer function and State-space modeling of BLDC motor.

5. Conclusion

The performance evaluation results show that, such a modelling is very useful in studying the drive system before taking up the dedicated controller design, accounting the relevant dynamic parameters of the motor. The paper presents an implementation of BLDC motor dynamic model, by using the transfer functions, transfer equations and state space modeling using MATLAB-SIMULINK in which all methods performed well and every method has its drawbacks. An inverter mathematical model is also simulated in MATLAB-SIMULINK with corresponding encoder, current controller and HALL sensor and back-EMF generation. Motor parameters of real BLDC motor is used and verified as per values in the data sheet. From the results obtained from three modeling techniques of BLDC motor, state space modeling worked well, it is efficient methods to model BLDC motor.
