改进的速度调节器在直接转矩控制中的应用

本文设计了一种改进的模糊自适应PID速度调节器，应用于异步电机直接转矩控制系统中。解决了常规模糊控制器在电机直接转矩控制过程中，特别是起动过程中因参数不变带来的超调量大、响应慢、不稳定性等问题。仿真试验结果验证了所研究设计的控制器的有效性。系统在动态响应、抗干扰能力、增强鲁棒性等方面均获得了满意的效果。

Direct torque control system based on an advanced speed transducers

This paper presents an adaptive PID fuzzy logic speed controller which is applied to direct torque control system.It solved the problems such as the big overshoot,slow speed corresponding,unsteady and so on,which are brought by fixed parameters in the process of DTC control in motor and especially in starting up.The results of the simulation demonstrate the validity of controller designed in this paper.The system has got a more satisfactory result of dynamic response,strong anti-interference and strong robu...
