Digital Redesign of Existing Multiloop Continuous Control Systems Via Continuous Frequency Matching.

Abstract

The problem of converting existing multiloop continuous control systems into digital control systems is considered. The objective of this paper is to develop a computer-aided method for synthesizing the pulse-transfer function of the digital controllers. This is done by matching the continuous frequency responses of the digital control system to those of a continuous system with a minimum weighted mean square error. Formulas for computing the parameters of digital controllers are obtained as a result. An example of digitalizing the existing continuous flight controller for the longitudinal YF-16 aircraft is considered and the results are compared with those obtained by previous methods. (Author)
