The theory of soft variable structure control, which produces robustness to parameter variation and fast transient response, is discussed in this thesis.
The digital implementation techniques are presented in the aspects of sample rate, prefilter design, hardware selection, and microprocessor arithmetic operation.
Simulation and experimental results showed good performance in negative speed range, but this controller created unwanted high armature current fluctuation in positive speed range. The reasons turned out to be the limitation of sample rate, noise from the tachometer, and high gain at positive speed. / Master of Science / incomplete_metadata
