The piezoelectrically actuated system has non-linear and time-varying behaviour, hence it is difficult to establish an accurate dynamic model for a model-based sliding-mode control design. In this study, a model-free adaptive sliding controller is proposed to control the piezoelectrically actuated system. This control strategy uses the functional approximation (FA) technique to establish the unknown...
Aimed at the problems, such as the poor synchronization performance of heavy crane being operated coordinately and huge amounts of on-line calculation using the existed relative coupling strategy, a position synchronization controller based on adjacent relative coupling strategy and backstepping is designed. The simulation model is constructed in Matlab/Simulink environment, and the Simulink results...
