Combined PWM Motor Control Study and Application in EPS


Article Preview

The power switch circuit of electrical power steering (EPS) is analyzed. A kind of PWM hybrid control algorithm combining the Unipolar reversible PWM mode of brush DC motors with its bipolar reversible PWM mode is put forward in this paper to improve the performance of current EPS system. The basic switch principle between Unipolar and Bipolar PWM mode is that the voltage during the switch process remains constant. The switch process and practical application of DC motor with Uni-Bipolar hybrid control mode in EPS is analyzed. The results show that PWM hybrid mode has exhibited good performance in vehicle electric power steering system.
