Low speed control of servo systems is required in some applications. Motor speed is generally acquired from the so-called M method, which averages the number of pulses from the coupled encoder by a fixed time period. As a result, a long detection delay time, due to speeds lower than the minimum measurable value determined by the sampling frequency and the resolution of the encoder, may degrade the...
This paper deals with the linear model-following control (LMFC) of a class of discrete systems which have the two-time-scale (TTS) property. It is shown that, under certain sufficient conditions, the proposed reduced-order LMFC can force the slow subsystem of the plant to follow the stable model asymptotically. Both state feedback and observer-based feedback control are considered. An example [8]...
