摘要
为了提高对交流异步电机的矢量控制能力,采用新型DSP芯片TMS320F2812并将一种具有自适应调整能力的模糊PID控制器应用于其中。该控制器将模糊控制原理与常规的PID控制算法相结合,通过模糊规则参数修正算法实现了对PID参数的在线调整,使系统具有自适应能力,从而改善了传统PID控制器在电机参数改变时鲁棒性较差、抗干扰能力差等不足[8]。实验结果表明,该自适应模糊PID控制器较常规PID控制器具有更好的控制效果。
In order to improve the capacity on the exchange AC induction motor vector control, using the new DSP chip TMS320F2812, and a self-adaptive capacity which applies fuzzy PID controller. The controller will be the principle of fuzzy control and conventional PID control algorithm for combining the parameters of fuzzy rules through amendments to the PID algorithm to adjust parameters online, the system with adaptive capability, so as to improve the traditional PID controller in the electrical motor parameters change less robust, antijamming capability, such as lack of large deviations. The experimental results show that the self-adaptive fuzzy PtD controller than the conventional PID controller has a better effect.
