This video continues the case study of video [PIintu1EN], where proportional-integral control of a (dominantly) 1st-order process was designed via intuition and trial-and-error. In here, the improvements by using antiwindup when subject to saturation are intuitively explained and checked (no theory on antiwindup back-calculation method is presented); also, a two-degree-of-freedom PI $u(s)=br(s)-y(s)+(1∕s)\cdot (r(s)-y(s))$ is tested to diminish overshoot in setpoint response while keeping a fast integral-action correction for good input disturbance rejection performance.
