Description and applications of a computer program for control systems design

A General, Multipurpose Simulation and Control PackagE (GEMSCOPE) is described which assists with the design, analysis and digital simulation of linear, time-invariant dynamic systems. The process model may be defined in block diagram form with transfer functions for each component, or in standard state-space form. Options are included for generating the optimal regulatory control matrices, determining the state feedback matrix for non-interaction, reducing the order of the model, and calculating the open or closed-loop system response. GEMSCOPE has proven useful for student education and for the design of practical control systems. Experimental and simulated data obtained by applying GEMSCOPE techniques to computer controlled pilot plants at the University of Alberta demonstrate the validity of the methods and the significant improvements possible through the use of modern control techniques.
