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...
This paper presents the modeling and design of a periodic output feedback (POF) controller to suppress the vibrations of a smart thin walled composite box beam. Collocated piezoelectric patches are bonded as sensor / actuator to the master structure at a certain finite element location on the beam, i.e., nearby the fixed end of the composite box beam. The beam structure is modelled in state space...
Active vibration control is one of the interesting problems for control engineers. The problem is tackled by making a smart, adaptive and self-controlling structure that requires robust controller. The newly invented second order sliding mode controller (SSMC) not only retains the robustness properties of the classical sliding mode controller (SMC) but also eliminates the drawback of the SMC that...
