Design of Heterogeneous Drive System Based on Object-oriented Devices and Speed Sensor

We present a smart motor architecture that incorporates a motor, driver, controller, and communication interface into a single control unit and implement virtualized motor driving. A new pulse width modulation (PWM) technique, called PK modulation (PKM), which is traditionally used as a power supply and is equipped with a communication functionality, is proposed. With this new technique, a multimotor driving system capable of driving heterogeneous motors (such as an AC motor and a DC motor) simultaneously is implemented. The driving system using this smart motor architecture can freely accommodate any change in the number of motors driven, relying solely on the power bus. Other advantages include a simplified driver, effective control of the power signal interference, and reduced number and weight of control lines. In this work, MATLAB/Simulink is used for signal analysis. MCU ATMEL328PU is chosen as the central controller for hardware implementation. The feasibility of the system architecture is verified as well.
