中心是围绕积分饱和问题积分作用——积分就是“重新调整”比例带。积分饱和——调节器的非线性特性被大的偏差信号所饱和,甚至当偏差降低而趋近于零以后,积分器仍使输出连续增加至饱和值。积分器在偏差的方向改变以前是不会开始“泄放”的。这一结果是高度非线性的而不会在一般线性调节器中出现。
The center is centered around the issue of integral saturation - the integral is the “readjustment” proportional band. Integral Saturation - The non-linearity of the regulator is saturated with a large deviation signal, and the integrator continues to increase the output continuously to a saturation value even as the deviation decreases toward zero. The integrator does not begin to “bleed” until the direction of the deviation changes. This result is highly nonlinear and does not appear in typical linear regulators.
