典型二阶积分对象的新型控制策略

针对工业控制中常见的一类具有时滞的二阶积分对象，根据内模控制原理，提出一种新型控制策略。在该结构中，由参考模型来实现系统期望的设定值跟随响应特性，利用内模控制鲁棒性强的特点来抑制参数变化和干扰对系统的影响，从而使系统获得良好的干扰抑制特性和鲁棒性。调节参考模型参数和内模控制器参数，可使系统同时具有良好的设定值跟随特性和干扰抑制特性。仿真结果表明了方法的优越性。

New control strategy for typical second-order integrating plants

A new control strategy is proposed for typical second-order integrating plants with delay in industry according to the internal model control principle.In the structure, the expected set point following characteristics is obtained by reference model, good disturbance rejection characteristics and robust stability of system can be achieved.Good performance of both set-point tracking and disturbance rejection characteristics can be achieved simultaneously by the adjustment of the reference model and internal model controller parameters.The simulation results demonstrate the superiority of the proposed method.
