In this paper, an intelligent electric power steering system use with Permanent magnet synchronous motor drive is proposed It is to replace a traditional hydraulic power steering system and implemented in a real light hybrid electric vehicle for automotive application. Some control Technique is applied to yield basic assist logic, return compensation logic, damping compensation logic, and inertia...
This paper presents the robust current and torque controls for a satellite reaction wheel system driven by permanent magnet synchronous motor (PMSM) is presented. First, the motor nominal key parameters are estimated, and the digital signal processing (DSP)-based PMSM driven reaction wheel system using intelligent power module is established. In the proposed robust current controlled pulsewidth modulated...
EV with 4 in-wheel motors has advantages of system's light weight because it has respectively independent control system. But it is difficult that EV has to control four in-wheel motors at once. The speeds of four in-wheel motors are different each other, because the disturbance and over wheel of four in-wheel motors are not the same. EV is necessary to control synchronously. Velocity differences...
