| Summary: | 碩士 === 元智工學院 === 電機與資訊工程研究所 === 84 === Parameter variation in the load of a dc servo motor system
requires a robust controller. In the thesis, a robust dc servo
motor velocity control system with sliding mode control is
presented. First we obtain the transfer function of dc servo
motor system and select appropriate variables to find a state
variable description which is suitable for the application of
sliding mode control method. According to the selected feedback
signals, we define the sliding variable, then a sliding mode
control algorithm will be designed to satisfy the condition
which guaratees the sliding variable reachs and sustains on the
sliding surface. Experimental results shown that the control
system in the sliding mode has achieved robustness against
parameter variations and load disturbances.
