    This paper considers the problem of matching a system under control to a model using output feedback when both the given system and the model are described by nonparametric models, such as their impulse response matrices. The problem of matching is reduced to that of solving a linear system of equations by choosing a set of samples of the response impulses. The ``condition number'' concept of nume...

    Chopper-controlled dc motors have a wide field of application as variable speed drives. The techniques used for chopper control of dc power make use of pulse-width modulation (PWM), pulse-frequency modulation (PFM), and current-limit control. Of these, the pulse-width modulation and current-limit control are more widely used. View full abstract»
