在控制系统ＣＡＤ和实际电路设计经验基础上，针对广泛使用的连续控制系统中有源滤波和校正网络电路的工程设计，提出了一种实用的优化设计ＣＡＤ方法。它根据网络的频域要求建立目标函数，在常用有源ＲＣ电路结构和电阻电容标称值数据中，寻找目标最佳电路。同时进行参数误差因素分析、稳健性比较，以及灵敏度分析。仿真和设计实例表明，本方法和软件设计是可行的，具有实用、简便、规范化的特点。

On the basis of control system CAD and engineering experiences of circuit design, the paper presents a kind of practical optimum CAD method to design active filter and correction network circuits, which have been widely used in continuous minimum phase control systems. Firstly it sets up value functions of design according to the desired network performances in frequence domain, then it searches optimal solution within the circuit sketches available and nominal values of resistors and capacitors. It also takes parameter errors and robustness of circuit performances into consideration. The simulation and design cases prove that the method is feasible, practical and simple.
