不变

The relationship between the error signal and gain parameters of PID controller is nonlinear, and , a normal controlled system＇ s step response figure , under the condition of ideal change of the three PID gain parameters in the different time , PID con troller.

但是，目前使用的PID控制器大多仍是传统的线性PID 控制器，其控制信号是通过将参考输入与被调节量的偏差及其微分、积分进行简单的线性组合来生成的，而且PID控制器的增益参数在系统动态响应过程中是固定不变的，不能反映偏差信号的变化l2j。

Valuation of movement probability has remained difficult to solve up to now without appropriate solution given to it.Today the movement probability used in ore-drawing simulation is still with traditional valuation all through,but it is unadaptable to mining simulations nowadays.
