Real-time CAD of control systems achieving cooperation of modeling and design of controllers

Development of a CAD of control systems which realizes coordination of modeling of plant and design of controller is introduced. It enables us to do not only analysis of control systems and design of controllers but also online modeling of plants in the same environment. By utilizing this software, the control engineer is able to repeat the procedure of design of control systems efficiently to archive the best performance, which depends on the controller as well as the model of the plant. It is also shown how to improve the speed of computation by introducing the technique of memory management for real time control and how to change the parameters of the controller without stopping real time control.
