Abstract: The motor-controlled steering wheel system based on
TMS320F2812DSP is a system using Digital Signal Processor to control the motor in order to achieve the simulation of a steering wheel system. Master chip is TI's C2000 series on TMS320F2812, using ordinary DC motor coupled with incremental rotary encoder and steering wheel with coaxial. When artificially rotating the steering wheel, the encoder sends signal from time to time back to the 2812 which comes with the QEP module, and then by controlling the PWM duty cycle modulate the output voltage in order to achieve changes in the motor speed and torque, allowing users to experience the feel of rotating the steering wheel.
Key words TMS320F2812, DC motor, Incremental rotary encoder, steering wheel ,QEP module, Pulse Width Modulation
