Abstract
In this study, a simulation program for hydraulic control systems was developed. By using this program, the operator is able to simulate dynamic performance of the systems without possessing special knowledge of software or control engineering. The program was developed for use on the most conventional type of personal computers. The simulation proceeds with each operation in a very simple manner based on the block diagram representation of systems. For these procedures, a graphical user interface was adopted in the program and, as a result, almost all operations for the simulation can be done by using window facilities on the display. As main features or functions of the program, it is possible to simulate pipeline elements, various kinds of nonlinear elements and discrete time control systems.
