| 摘 要： | 针对控制对象存在大惯性、纯迟延和参数时变的情况,对典型PID串级控制系统加以改进,提出了模糊Smith串级复合控制策略,将Smith预估器引入副回路并利用模糊控制器作为主控制器。仿真结果表明,该控制策略能有效克服大纯滞后对控制系统稳定性的影响,且具有动态性能好等特点。

| Abstract: | The novel fuzzy smith cascade compound control policy based on typical PID control strategy is proposed, which is aimed at the inertia property, large delay and timevarying parameters of cascade control system. Simulation results show that it is effective to overcome the influence of time-delay on stability of control system and strong robustness and good dynamic performance. |
