Tracking enhancement with deadbeat feedforward compensation

The implementation of a feedforward compensator to minimize the overshoot and settling time of a sampled-data tracking system is discussed. Deadbeat controller design techniques are utilized to determine the compensator coefficients for single-input-single-output and time-invariant plants. Relationships for the compensator coefficients that are a function of the target dynamics, sampling interval, plant delay, and settling time are obtained. If a solution is feasible, the settling time can be chosen to satisfy a maximum overshoot constraint
