摘要
由于三自由度转台是非线性系统,难以建立精确的数学模型。为了克服常规PID控制器在非线性三自由度转台系统中的控制不理想的问题,将模糊PID控制和常规PID控制相结合,设计了混合型模糊PID控制器,通过MATLAB实现了混合型模糊PID控制系统的仿真。仿真结果表明:利用混合型模糊PID控制三自由度转台系统,具有响应快、超调量小、鲁棒性强等优点。
Because the Three-axis Table is non-linear system,establish an accurate mathematical model is difficult.In order to overcome the effect of traditional PID control is not satisfying in the control of nonlinearity Three-axis Table System,combined the fuzzy-PID control with conventional PID control,composite Fuzzy-PID controller was designed and simulated by using the MATLAB.The results show that the Three-axis Table System with the Composite Fuzzy-PID controller has a fast response,slight overshoot and high accuracy.
