A Practical Reference Model for Control System Design

The present paper is concerned with the design specifications in terms of pole-locations in so-called "digital design," as opposed to "digital redesign," of control systems with the sampling-period explicitly expressed. Effects of the sampling-period on pole-locations of systems expressed in the delta operator are studied with particular reference to the design of a type-l yawing-angle control system using a single axis deflecting air-jet nozzle. Performances of the digital controller are studied through experiments, which show that the proposed digital controller gives performances comparable to continuous-time cases for reference command tracking using relatively large sampling periods, while the period should be as small as possible for disturbance rejection.

In this paper, a new variable gain PD controller design scheme is proposed, whose PD parameters are tuned corresponding to the jib length, the rope length and the jib angle. Since the jib angular acceleration is utilized as the control input, PD controller is employed which is removed the integral action from the PID controller. The PD parameters are adjusted in an on-line manner based on the pole-assignment control scheme. Furthermore, the effectiveness of the newly proposed PD control scheme is numerically and experimentally evaluated on the sway control system of a lifted load for a mobile crane.
