ABSTRACT
Academic control groups have been developing computer-aided design packages for control system analysis, design, and simulation since the late 1960s, when interactive computing became a practical reality. The Database needs of the control engineering community differ radically from those of the commercial world which are already catered for by various existing facilities of this type. The necessary Matrix Manipulation Tools, which form the kernel of the current control system design and synthesis algorithms were provided by PRO-MATLAB. The nonlinear system analysis and design facilities developed by Atherton at Sussex were also considered to be a valuable component of the control engineer’s toolbox, and the self-tuning regulator design facilities, created by Astrom at Lund, Clarke at Oxford, and Wellstead at UMIST, were then becoming well-established in industry and formed further essential system control techniques. To ensure consistency, this new diagram will have the same number of input-output terminals as the original macro block’s ports.
