摘要
自抗扰控制器(ADRC)通过对模型不确定因素和外扰进行补偿,使得控制系统对外抗和不确定因素均有很好的适应能力。它能够有效控制多种工业上较为难控的对象,并表现出极强的鲁棒性和抗干扰性。遗传算法在参数寻优方面,有着其他算法无法比拟的全局寻优能力,本文给出了基于遗传算法的自抗扰控制器的参数整定,并将其应用在几类不同的对象当中,仿真实例表明了通过遗传算法整定的ADRC的良好控制效果。
Active disturbance rejection controller(ADRC) can effectively adjust uncertain factor and disturbance of the model by compensation.lt can effectively control many unmanageable model and shows its robustness and anti-disturbance to us.Genetic arithmetic have better ability of optimization in global than other algorithem. We present the parameter setting of active disturbance rejection based on genetic autithmetic and apply the method to some models .The result of simulation shows the good effect of ADRC set by genetic aurithmetic.
