A Smart Motor Driving System Using Pu's Count Modulation Multichannel Communication

摘要

In this paper, we propose a new-generation motor architecture (smart motor) constructed by first integrating a motor, driver, controller, and communication interface into a control unit, and then using Pu's count modulation (PKM) technology to replace the traditional pulse width modulation (PWM) technology to power a smart motor; the proposed motor architecture and PKM technology have a communication function. The purpose of this study is to virtualize the motor control through the design of the smart motor, while simultaneously driving the heterogeneous motor. However, the proposed PKM technology uses the master-servant communication architecture to transmit the message of only one smart motor at a time. Therefore, as the number of responding smart motors increases, the overall response time is directly increased; this indirectly affects the response sensitivity of the smart motor drive system. Another contribution of this paper is the proposal that the establishment of an ADALINE artificial neural network can facilitate a set of multichannel, parallel communication architectures for computing the signal from a sensor to reduce the overall communication time and increase system response capabilities; this system is called multichannel PKM (MPKM) technology. In the smart motor architecture, the drive system only needs power busbars, which can randomly increase or decrease the number of drive motors, simplify the drive program, control the power signal interference problem, and reduce the number and weight of control lines. At the end of this paper, the signal is analyzed using MATLAB/Simulink®, and the microcontroller (MCU) ATMEL328PU is used as the control center. The hardware of the architecture system can be used to verify its feasibility.
