Description: 在分析无刷直流电机(BLDC)数学模型的基础上,提出了一种无刷直流电机控制系统仿
真建模的新方法。在Matlab/Simulink环境下,把独立的功能模块和S函数相结合,构建了无刷直流
电机系统的仿真模型。系统采用双闭环控制:速度环采用离散PID控制,根据滞环电流跟踪型PWM
逆变器原理实现电流控制。仿真和试验结果与理论分析一致,验证了该方法的合理性和有效性。
此方法也适用于验证其他控制算法的合理性,为实际电机控制系统的设计和调试提供了新的思路。
-Based on the mathematical model of the Brushless DC motor(BLDC),a novel method for modeling and
simulation of BLDC control system was proposed.In Matlab/Simulink,by the combination of the isolated functional blocks
and S-functions,the model of BLDC could be established.In the double loop of control system,a discrete PID controller was
adopted in the speed loop and a current controller was completed in the current loop on the principle of hysteresis current
track PWM inverter.The reasonability and validity were testified by the coincidence of the simulation and experimentation
results and theory analysis.This novel method is also suitable for verifying the reasonability of other control algorithms and
offers a new thinking for designing and debugging actual motors.

Description: This simulation demonstrates the use of the PMSM in a closed-loop speed and current control on a 1.1 kW 3000 rpm industrial motor. A three-phase motor rated 1.1 KW, 220 V, 3000 rpm is fed by a PWM inverter. In this simulation, the whole system is built entirely with standard Simulink blocks (without resort to blocksets).
