T1is the lead time constant. T2is the lag time constant. Tsis the compensator sample time. From the discrete transfer function, the compensator equations are defined using the forward Euler method: ⎧⎪⎪⎨⎪⎪⎩x(n+1)y(n)=(1−TsT2)x(n)+(TsT2)u(n)=(1−T1T2)x(n)...

Although similar idea is straightforwardly extended to discrete-time systems, it is not very clear whether sampled-data stable inversion approximates the continuous-time counterpart. This is because there is no simple relation between zeros of the continuous-time transfer function and zeros of the ...
Bumpless Control Transfer Between Manual and PID Control Achieve bumpless control transfer when switching from manual control to proportional integral derivative (PID) control. The model uses the PID Controller block in Simulink® to control a first-order process with dead-time. ...
Another approach is to model the delay by a rational polynomial transfer function using a Padé or similar approximation and then estimate the time delay as part of the system parameters Agarwal and Canudas (1987), Ahmed et al. (2006), Gawthrop and Nihtil (1985). In Baysse et al. (...
