摘　　要：传统的PID控制器无法适用于各种形式的积分系统,或者鲁棒性不高,为时滞积分系统设计了一种采用直接合成法的PID控制器。首先,比较积分系统与PID控制器的特征方程,期望的特征方程包含多个极点,且此类极点均位于相同的期望位置;然后,对参数进行调节以获得期望的系统鲁棒性。将控制器方案应用于多种传递函数进行仿真实验,结果显示了算法可适用于多种积分系统,且保持了较好的鲁棒性。Traditional PID controller could not be applied to all kinds of integrating systems, or is not robust, a PID controller using direct synthesis algorithm is designed for the integrating system with time delay. Firstly, the characteristic equations of integrating systems and the PID controller are compared, the desired characteristic function consists of multiple poles and the poles are located at the same desired location; then, the parameters are tuned to get the desired system robustness. The proposed method is applied to multiple transfer equation to do experiments, and the results show that the proposed method could be applied to multiple integrating systems, and has good robustness.
