由于行波超声波电机存在时变性、非线性等特征,为了得到更加稳定的转速输出,利用神经元的自学习能力在线寻找最优控制参数,是提高电机控制效果的有效途径。因此通过分析单神经元PID控制器优缺点,可以利用单神经元PID和PI构成复合控制器,提高行波超声波电机的速度控制效果,而且结构简单,有利于商品化。
The output characteristic of traveling-wave ultrasonic motor is nonlinear and time-varying. In order to obtain the stable speed output, it is the effective way utilizing the neuron seeks the optimum control parameter on line. Just because above the reason, through in the analysis the single neuron PID controller's merits and drawbacks, A single neuron PID and PI composite controller is designed and studied. The composite controller enhances speed control's effect of traveling-wave ultrasonic motor.
