采用以时间最优为指标的断续控制器作为系统的前馈 ,根据对象状态的条件 ,判断和变换断续控制器的作用 ,补偿连续控制器的控制值。这种连续控制与断续控制混合的控制系统 ,把 PID控制器与对设定值变化及对干扰抑制实现快速控制的邦 -邦控制器结合起来 ,能够快速地实现系统动态调节 ,且超调量小 ,并克服了由于控制器硬件的某些限制 ,不能较大范围改变控制信号的缺陷 ,在实际过程控制中达到了很好的动态和稳态响应。
Using the intermittent controller with the optimal time as the feedforward of the system, the function of the intermittent controller is judged and transformed according to the condition of the object state, and the control value of the continuous controller is compensated. This continuous control and intermittent control mixed control system, the PID controller and the set point changes and suppression of interference to achieve fast control of the state - state controller, the system can quickly achieve dynamic regulation, and overshoot It overcomes some limitations of the controller hardware and can not change the defect of the control signal in a wide range. It achieves good dynamic and steady state response in the actual process control.
