TLDR
A simulation teaching experiment to control a gantry crane system is proposed, using a Posicast feedforward technique to enhance the setpoint tracking response and a PID controller is used in the feedback loop to deal with disturbance rejection.Abstract:
A simulation teaching experiment to control a gantry crane system is proposed. The control is performed both in open-loop and closed-loop. The open-loop control is based on the Posicast feedforward technique and the closed-loop control uses a two-degrees of freedom configuration. Posicast control is used as a pre-filter outside the feedback loop to enhance the setpoint tracking response and a PID controller is used in the feedback loop to deal with disturbance rejection. Students are required to use a gantry crane animation, to visualize its movement promoting a better perception and control techniques understanding. The experiment was performed by undergraduate feedback control students which provided learning results through a survey questionnaire.read more

Posicast Control of Damped Oscillatory Systems
TL;DR: In this article, a method for producing dead-bea response in a lightly-damped oscillatory feedback system is presented, which consists of exciting several transient oscillations, at closely spaced times, with magnitudes and phases so adjusted that the resultant sum of the transient oscillation phasors is zero.
