摘 要: | 采用实际模型简单控制的策略,针对分数阶系统提出一种基于预期动态方程的二自由度P ID整定方案(DDE)。通过选取预期动态方程系数,将控制器参数与系统控制要求建立联系,确定各个参数的取值规则。8个分数阶模型的控制仿真结果表明,用DDE法整定的整数阶二自由度 PID控制器可以使系统满足预期动态,并且该控制器具有与分数阶P ID相当或较其更好的控制效果。

Abstract: | Using the actual model simple control principle ,this paper proposes a two degrees of free-dom proportional-integral-derivative (2-DOF PID) based on desired dynamic equation (DDE) for frac-tional order system (FOS) .The controller parameters and control requirements are connected by se-lecting the coefficient of DDE ,and tuning rule is derived .Simulation results show that system re-sponse can satisfy the desired dynamic behavior and the DDE method has near or better transient process than fractional order PID . |

Keywords: | fractional order system desired dynamic equation method PID controller 2-DOF |
