Proportional Integral-Differential Controller with Single-Neuron PID Controller for Speed Tracking Control of Induction Motor

运用常规的控制方法很难使普通感应电机转子的速度或位置在任何时候都能自动、连续、准确地复现给定信号的变化规律．讨论了一种采用单神经元PID（比例－积分－微分）调节器来实现感应电机速度跟踪的方法．首先介绍了单神经元PID调节器的基本工作原理，然后构造了采用单神经元PID控制的感应电机调速系统的仿真模型，最后通过计算机仿真，对此种调节器在感应电机调速系统中的应用进行了分析，仿真结果验证了此调节器可使感应电机具有很高的跟踪性能，整个系统对参数变化不敏感，具有良好的自学习与自适应能力．

Due to the nonlinear characteristics, in the speed tracking control or the location tracking control,the rotor speed or the rotor location of the common induction motor is hard to duplicate the variable rule of the given signal by using the routine control methods. A single-neuron PID (proportional-integraldifferential) eontroller used for high performance speed tracking control of induction machine was discussed.Firstly, the principle of the single-neuron PID controller was introduced; then, the simulation model of the induction motor control system with single-neuron PID controller was constructed, by means of computer simulation, the application of this kind of controller in the speed tracking control of induction motor was analyzed. Results of simulation prove that this method can make the drive system of induction motor the one with high tracking precision, strong robustness, and the ability of self-learning and self-adaptation.
