Abstract :
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 compensation logic in an assist steering system according to steering wheel angle and vehicle speed. The PMSM drive in an EPS system can be considered as a torque amplifying and tracking system. When the driver of the vehicle moves the steering wheel, a torque sensor in the steering mechanism sends a torque signal to the EPS controller. The DSP inside the EPS controller receives the torque input and sends it to a torque command algorithm. The torque command algorithm processes the torque input, along with other inputs, such as vehicle speed, motor speed, and generates a torque command to the PMSM drive subsystem. The PMSM drive controls the PMSM motor to generate an output torque that tracks the desired torque demand. In this paper Section 1 describes Introduction, Section 2 describes EPS system description & hardware, Section 3 describes control strategy& Section 4 describes conclusion.
