In this paper we discuss some aspects of the computer-aided design of control systems. We focus our attention on design and synthesis programs intended to run on mini- and microcomputers. In particular, a synthesis program, based on simulation and optimisation, is shown to have many capabilities, enabling the designer to solve real control problems. A designer-oriented hardware environment that allows readily available design facilities is discussed. Moreover, an example of a design program and a synthesis program is described, and our experiences with these programs in the education of students and in the research projects in our laboratory are reported.
