SUMMARY:

This thesis presents a novel compensation approach for receptance-based second-order systems with long input delay and unknown dead-zone input nonlinearity. The approach is based on a filtered Smith predictor for systems with long input delay based on the receptance model. An innovative discrete-time adaptive strategy approach for dealing with unknown input dead-zone is also based on a receptance model realization. The receptance-based second-order model is used in several fundamental applications, including active control vibration of mechanical vibrating systems. A filtered prediction error that considers the effects of time delay can be applied to pursue state feedback design for active vibration control purposes in the proposed approach. The dead-zone compensation is treated by a discrete-time state observer, which is based on displacement, velocity, and control effort signals to estimate the unknown parameters used in an adaptive algorithm. The main contribution of this work is to combine an unknown dead-zone adaptive mechanism and a receptance-based time delay compensation in a unified
design. Some numerical examples illustrate the effectiveness of the innovative
proposed approach.
