【摘要】 高阶对象是比较特殊的控制对象之一,其特殊的性质使得对它的有效控制难以实现。本文将二阶线性自抗扰控制器(ActiveDisturbance Rejection Controller,ADRC)应用到一类由惯性环节串联形成的高阶系统中。仿真结果表明二阶线性ADRC能够实时准确地估计出高阶系统扰动并加以补偿,不依赖于被控对象精确的数学模型,具有很好的控制效果和良好的性能鲁棒性,从而验证了二阶ADRC对高阶系统控制的有效性。更多还原

【Abstract】 High-order system is difficult to be controlled effectively for its special characteristics.In this paper,the second-order linear Active Disturbance Rejection Controller(ADRC) is applied to the control of the high-order systems which are constructed by a series of inertia elements.The simulation results show that the second-order linear ADRC can estimate precisely and compensate both the inner and outer disturbance instantly,and does not depend on the accurate model of the plant,and plays good performance and robustness in the control of high-order system.更多还原
