A linear-analysis subsystem for CSSL-IV

Abstract

In order to better address the needs of the controls engineer, CSSL-IV (Continuous System Simulation Language-version four) has been enhanced to include software tools for the design, optimization, and evaluation of linear automatic control systems. The CONTROLS-LAB subsystem of CSSL-IV provides the foundation for a workbench which will enable the engineer to design, optimize, and evaluate control systems before committing to the expensive prototype phase of product design. Both continuous-time and discrete-time systems can be modeled and either time-response or frequency-response results displayed graphically for easy understanding. Many of the CSSL-IV vector and matrix tools have been collected under this subsystem and expanded to include the current state of the art in control systems. The author presents an overview of the capabilities and features of the CSSL-IV/CONTROLS-LAB designer's workbench.<>
