摘要
提出了一种调整PI系数的无刷直流电机控制器的新方法,使用TI公司的TMS320LF2407A数字处理器为核心芯片和PWM控制技术来实现无刷直流电机的控制,并且利用人工神经网络来确定整个系统的最大超调量和调整时间,从而得到不同的Kp-Ki对。
In this paper,a new method of tuning Proportional Integral（PI） coeff cients for a brushless DC motor drive is proposed.The DC motor can be controlled by TMS320F2407A processor core chip and PWM control technology.And artif cial neural network is used to identify the whole system maximum overshoot and settling time for different Kp–Ki pairs.The optimal values are obtained by genetic algorithm.Experimental results are given to show the validity of this method.
