In this paper, we introduce the design method for multirate output feedback based frequency shaped sliding mode control. A switching type reaching law has been used for the vibration suppression of the smart structure. The frequency shaping approach is used to suppress the vibratory modes of smart structure excited during the sliding mode.
In this paper, a method is presented for frequency-shaped sliding mode control using output feedback. A compensator is introduced in the sliding surface to attenuate the certain frequency component of the sliding mode dynamics. The output is measured at a faster rate than the control input to estimate the states of the system. The proposed output feedback frequency-shaped sliding mode controller is...
A reaching law based discrete sliding mode control is designed for piezoelectric actuated structures to suppress the vibration in the presence of disturbance. Recursive least square method is used to identify the model and the states are estimated using Kalman filter. The performance of the controller for vibration suppression and disturbance rejection is demonstrated through simulation and experimental...
