Permanent Magnet Synchronous Motor (PMSM) as the key component of the Electric Vehicles (EVs), has numerous advantages over other synchronous motors. Fault diagnosis is essential to guarantee the safety and continuity of the operation for EVs. An undetected fault in the PMS M system may lead to high repair cost, or even catastrophic failure. Among lots of faults in the PMSM, the most serious are short...
In this paper, the tracking control for a mechanical system with friction and backlash is considered. Friction and backlash nonlinearities often act on the main obstacles for high precision control. Based on the LuGre friction model and the Backlash model, a robust adaptive control algorithm is developed to compensate for friction and backlash nonlinearities by using backstepping design techniques...
A control system of Tightening Machine scheme is analyzed and a new control system based on CAN bus is designed in this paper. Compared with past design, this system has High Anti-interfering, High Structural Stability and Low Cost capability.
The attitude tracking control problem of the spacecraft using magnetic actuators is considered in this paper. We design the adaptive control law, which incorporates a velocity-generating filter from attitude measurement, to ensure the asymptotic convergence of the attitude and angular velocity tracking errors despite unknown spacecraft inertia. Simulation results demonstrate the practical applicability...
