CAN- Based Synchronized Motion Control for Induction Motors - jithincissac000 - 08-16-2017 CAN-based Synchronized Motion Control for Induction Motors Introducton A control area network (CAN) based multi-motor synchronized motion control system with an advanced synchronized control strategy is proposed in this article. adjacent cross-coupling control strategy is incorporated into into the sliding mode control architecture to achieve it. Sliding-mode adjacent cross-coupling control strategy of multi-motor synchronization: Networked control system is flexible and expandable. to improve motion accuracy, applying the advanced motion control strategy to the distributed CAN bus synchronized motion control system becomes very important. Adjacent cross-coupling control strategy: If there are n induction motors in the system, each controller of the multi-motor motion control system is designed to stabilize its speed tracking, while synchronizing the speed between this controller and other two controllers with adjacent sequence number. the synchronized motions of all motors can be achieved by using the above strategy. Sliding-mode adjacent cross-coupling controller: When using this strategy, the i-th motor synchronization speed controller includes two parts: one tracking error controller to track the desired speed accurately and two synchronization error controllers to eliminate the synchronization errors between the controlled motor and its adjacent motors. Multi-motor synchronized motion control system based on CAN bus Applications of CAN bus: The CAN bus is a serial communication protocol which supports distributed real-time control with low cost and high reliability. In the system, the central industrial computer receives speed measurement messages of each motion controller and sends synchronization messages to all motion controllers via the CAN. new speed command adopting the adjacent cross-coupling control strategy can be calculated based on the prsent recieved signals through the CAN. The motion controller has 32 mailboxes that can be configured to transmit or receive messages. On recieving complete speed commands, the motion controller can select the useful command according to the ID number of the mailbox. The single motion control system: The single-motor control system for an alternating current (AC) induction motor consists of a TI DSP TMS320F2812, the protection circuit, the insulated gate bipolar transistor (IGBT) power stage, the AC induction motor with optical encoder and hall sensors. It converts the instantaneous motor speed measurement to a packet, and then send it to the central controller and also sends out pulse width modulator (PWM) signals to the power stage to drive the induction motor. The multi-motor synchronized motion control system: It consists of consists of the CAN bus network, the industrial computer, and some single motion control systems.The communication channel between the industrial computer and the motion controller is the CAN bus. report: http://springerlinkcontent/91430u2022g00144/ |
