"阻转矩负载计算机速度调节拖动系统软件设计研究"

This paper is a detailed study of the design and implementation of a resistance torque load computer speed regulation system using software control. The study is conducted at the Northern Science and Technology College of Shenyang Aerospace University. The research is based on the fundamental principles of motor and power transmission systems and aims to achieve smooth control of forward and reverse starts, acceleration, deceleration, and stopping, as well as emergency response capabilities such as overvoltage stopping, overheating stopping, blockage stopping, and limit stopping. The design is centered around the mechanical characteristics of a three-phase asynchronous motor and utilizes a rotor circuit with serially connected symmetrical resistors for speed regulation and energy consumption braking. The main circuit employs a three-phase bridge fully controlled rectifier circuit. In terms of software design, the paper utilizes C language and Keil software for programming, along with corresponding program flow charts. The hardware structure is designed to be as simple as possible, while maximizing the functionality of the software, resulting in significantly improved system reliability. Key words: resistance torque load, computer speed regulation, rotor series resistor, energy consumption braking. In summary, this research provides a comprehensive analysis and design of a resistance torque load computer speed regulation system, with a focus on both the hardware and software aspects. The implementation of this system has potential applications in various industrial settings, contributing to the advancement of control and automation technology.
