High-speed PC-based CAD for motor drives

Following on from an EPE-91 paper (Miller et. al, 1991) describing high-speed integrated CAD environment for switched reluctance and permanent magnet brushless DC motor drives, this paper reports the extension and development of these design techniques in two selected areas: (1) the design and modelling of DC commutator motors and their drives; and (2) the dynamic modelling of the complete control system of switched reluctance motors over long periods. As in the previous paper, the software engineering aspects are explained and emphasized, as these are crucial for the improvement in engineering productivity during the design process. However, the paper also describes new work in the area of electronic control of the switched reluctance motor, particularly in relation to the stability and dynamics
