Input Shaping Control

A poorly designed control system can lead to excessive residual vibration and long setting time. This paper investigates the effect of input shaping on control efficiency. To perform this investigation, we design a PD controller combined with input shaping for an inertia plant. We then subject it to four standard types of inputs. The responses of the control systems are described by analytical expressions. The performances of PD control and PD combined with input-shaping control are thoroughly analyzed and compared. Simulation results show that PD feedback control enhanced with input shaping minimizes overshoot and setting time.

Feedback Control Theory

A general algorithm is developed for input shaping on the basis of the deadbeat state feedback control theory in discrete-time. This algorithm is easily extended to generate input sequence robust to parametric uncertainties in a flexible structure. Numerical results are presented for systems with one and two vibratory modes.
