With the increasing complexity of modern command post, the space requirement for the shelter is also increasing. The expandable shelter solves the problem of the space requirement of the modern command post. The expansion controller is the control center of the expandable shelter and needs to realize its stable and reliable expansion action. This issue takes STM32 as the core, designs the expansion control system expansion controller, and designs the motor driver based on the full-bridge driver. Using the PWM control signal generated by the advanced timer of the MCU, combined with the control methods such as motor soft starter and feedforward controller, realizes the stable and accurate synchronous control of the expandable shelter.
