| 摘 要： | 在前馈加反馈的二自由度控制结构中,反馈PID控制器用于抑制负载扰动,同时使闭环系统有合适的鲁棒稳定性,而前馈控制器是在反馈PID基础上引入比例加权系数和微分滤波系数实现,目的是使设定值响应速度快且超调小.PID参数和前馈系数都是依时间绝对误差积的积分（ITAE）最优而得.针对工业上典型的一阶时滞过程,利用计算机优化和拟合运算,得到控制器的最优设定公式.仿真表明,建议方法对时滞过程是有效的.

| Abstract: | In two-degree freedom control structure,the feedback PID controller is used to suppress the load disturbance and to ensure suitable robust stability of the closed-loop system,while the feedforward controller is based on the feedback PID with a proportional weighting and derivative filter coefficients to achieve fast setpoint response and small overshoot.Both the PID parameters and feedforward coefficients are tuned by optimizing the integral of time multiply absolute error(ITAE).The tuning formulas for cont... |
