Abstract :
The authors present a design approach for the control of DC motors, based on optimal multivariable system theory. An optimal state-feedback control law is developed to achieve fast and stable speed regulation with minimum control effort. The basic feature of the system is the fast and accurate estimation of either the rotor speed or the armature current, using an optimal reduced-order observer. An application example and some digital simulation results, indicating the effectiveness of the system, are presented.<>
