discrete-time proportional-integral (PI) DC-DC voltage control with feedforward,FF. The feedforward input optimizes the transient response. The block can output a duty cycle or a current control signal. To avoid saturation of the integral gain, the block can implement anti-windup gain. ...

解决windup问题要回归积分器本身:由于积分器 \frac{1}{s} 本身是个不稳定环节,如果actuator达到limit了,那么反馈控制回路实际就被断开了,那么积分器的输出就会不断增长。那么为了实现anti-windup,我们需要设计控制回路或者某个装置使得积分控制器本身能够被稳定下来。能够实现这样效果的电路或者装置都起到了anti-wind...

Control performance, such as overshoot and settling time, is very similar to that determined by PID gain in the linear range. 展开 关键词: Anti-windup proportional-integral-derivative (PID) control integral state prediction variable-speed motor drives ...
Common anti-windup measures include: Disabling the error sum accumulation when the controller output is saturated Disabling the error sum accumulation until the Process Variable is within a certain range (known as the “controllable region) of the Setpoint ...
Anti-reset windup is that the integral term does not accumulate if the controller output is saturated at an upper or lower limit. Derivative KickAlthough the "derivative" term implies de(t)dtde(t)dt, the derivative of the process variable d(PV)dtd(PV)dt is used in practice to avoid a...
What’s up with the religion of peace and compassion? Let’s shed some integral light. SHIFT YOUR PERSPECTIVE The Transpersonal Workout: Less Pain, More Gain Jeff Salzman and Corey deVos For most of us, working out kind of sucks. Here’s a great way to more deeply engage your work...
