COINGRAD; Control Oriented Interactive Graphical Analysis and Design

Abstract

The computer is currently a vital tool in engineering analysis and design. With the introduction of moderately priced graphics terminals, it will become even more important in the future as rapid graphic interaction between the engineer and the computer becomes more feasible in computer-aided design (CAD). To provide a vehicle for introducing undergraduate engineering students to the applications of CAD in the automatic control area, a series of three programs--named Control Oriented Interactive Graphical Analysis and Design (COINGRAD)--has been written. These incorporate the basic calculations in this area, including time response, frequency response, and root locus; in addition, a limited optimization facility is included with the time and frequency response programs. The major features of the programs include graphic interactive capability and ease of operation for the user. (Author)
