模糊PID控制在直流调整系统中的应用

Application of fuzzy PID control in DC adjustment system

对双闭环直流调速系统中的控制方法进行了研究。目前双闭环调速系统所采用的大多是传统PID调节控制器,针对该类控制器在实际应用中处理动态非线性变化性能不佳的缺点,提出将模糊控制理论与PID技术相结合,设计了模糊-PID双控制器方案,改进后的方案既保留了常规PID控制器对稳态时静差的处理能力,又具备模糊控制对系统动态非线性变化的处理能力。仿真实验证明,该方法比传统的PID控制策略具有更好的控制性能。

Double Loop DC Motor system control method was researched.Double loop speed control system used mostly traditional PID regulator controller,for the poor performance of dynamic non-linear changes in the practical application of this type of controls,fuzzy control theory and PID technology combined design dual fuzzy-PID controller scheme,the improved scheme not only retains the conventional PID controller of the processing power of static error in the steady state,with fuzzy control of nonlinear dynamic system changes.Simulation results show that the method had a better control performance than the traditional PID control strategy.
