"基于单片机的悬挂系统设计：高性能、精确控制与广泛应用"

Abstract This project focuses on the design and development of a suspension system controlled by a microcontroller. By calculating relevant parameters and designing appropriate programs, the system is able to meet the performance requirements of the project. The core component of the system is the microcontroller, which is chosen for its high integration, cost-effectiveness, simple peripheral circuits, and efficiency, making it widely applicable in real-life applications. The suspension trajectory control system is a motor control system that allows objects to move in linear, circular, tracing, and other patterns within a 80cm x 100cm range, displaying the coordinates of the moving object during operation. In this design, the MSP430F1611 microcontroller is used to control the stepper motor, which is precisely measured by a multi-turn potentiometer for the position of the suspended object. A local closed-loop feedback control loop is introduced to correct errors, allowing for precise control of the object and accurate positioning of coordinates. Control signals are passed through an L298 drive circuit to operate the stepper motor and complete the specified actions. Additionally, a keyboard is used to input parameters for any desired coordinate point, with an LCD display showing the coordinates of the pen location in the suspended object. The software functionality module is responsible for controlling the position, velocity, direction, and motion time of the stepper motor. Keywords: microcontroller, stepper motor, algorithm.
