• Resumen

  • This paper describes a method of integrating various approaches to controller design into a singlemenu-driven graphical software interface for MATLAB. For convenience sake, the graphicalinterface is referred to as CADICS (Computer-Aided Design Integration of Control System). TheCADICS application package was developed under a Window-based environment to assistengineering students in designing control systems using MATLAB, but who do not have detailedknowledge of MATLAB commands. Two methods of the control system design that are normallytaught in engineering undergraduate control courses are incorporated into the program. In the firstmethod (Classical Control), the plant can be compensated by PID, lead or lag compensators.Users choose the type of compensator required and the compensator parameters are automaticallydetermined by the system so as to fulfil the design specification. In the second method (State SpaceRegulator), control is effected by state feedback, with or without a full-order observer. The paperhighlights the program environment and the data storage structure. A case study is described usingthe developed software (CADICS). The software helps to relieve the load on students to be familiarwith MATLAB commands. When used in a laboratory session to illustrate control principles,students will thus have more time to concentrate on the control theory rather than on the designtool, i.e. MATLAB
