碩士 === 國立成功大學 === 電機工程研究所 === 82 === In the thesis, we study the design method of the PWM controllers. First, based on digital-redesigned state-feedback controllers, one can translate the pulse-amplitude modulated sampled-data controls into pulse-width modulated controls extensively used in multivariable system. Nest, a newly digitally redesigned approach is developed for the discrete- time control of input time-delay systems. Finally, one can utilize the new method to translate the pulse-amplitude modulated discrete control into the pulse-width modulated control. Using the pulse-width controller, the states of controlled system closely match with those of the pulse- amplitude modulatelly controlled system for a relatively longer sampling period.
