电力传动系统的转矩控制器优化设计与实现
Optimization design and implementation of torque controller for power transmission system
摘要
Abstract
The rotating speed sensor of power transmission system may cause failure under severe environment,so the sys⁃tem may be limited by the low switching frequency at low running speed. For this problem,the traditional direct torque control system has high torque ripple due to the search of optimum motor parameters by means of single point. Therefore,the torque controller based on improved genetic tabu algorithm is proposed,which can control the motor torque,rotational speed and angle through the torque control system based on DSP. The torque control instruction is given based on the control scheme of the im⁃proved genetic tabu algorithm to realize the accurate torque control of the power transmission system. The PID controller based on the improved genetic tabu algorithm is adopted in the speed controller to improve the torque control performance of the power transmission system. The tabu searching method is used as the mutation operator of genetic algorithm to avoid the overshoot prob⁃lem existing in PID speed controller of the power transmission torque control system,make the torque controller have stable torque ripple at low running speed,and improve the stability of the power transmission system. The experimental results show that the method can effectively optimize the torque performance of the power transmission system,and obtain the smooth torque waveform.关键词
