The control performance of the reluctance actuator maglev system is seriously affected by inherent nonlinearities (e.g. hysteresis, eddy current, flux leakage, etc.) and external disturbances. To this end, paper proposes an enhanced unknown dynamics estimator (USDE)-based sliding mode (USDE-SMC) method a novel predictive-adaptive switching (PAS) controller (USDE-SMC-PAS). First, USDE incorporat...

We propose a model predictive control (MPC) method to compensate for the time-varying phase aberrations in sensorless adaptive optics (AO) system. The approximate point spread function (PSF) of imaging system with diversity is mathematically derived, and its validity verified. proposed MPC, which considers operating limits deformable mirror (DM), computes optimal applied voltage each actuator o...

The real-time control of water distribution networks for firefighting is an important but little-studied problem. Water utilities in England and Wales reduce hydraulic pressure to a minimum regulatory threshold order leakage avoid financial penalties. However, are not legally bound guarantee specific flow rates from fire hydrants, which poses risk firefighting. This study presents adaptive nonl...

Virtual coupling (VC) is an emerging concept and hot research topic in railways, especially for metro systems. Several unit trains VC drive with a desired minimum distance, they, as whole, are regarded single train. In this work, distributed adaptive model predictive control (AMPC) system proposed to coordinate the driving of each train VC. To obtain accurate parameters dynamics time varying en...
