用于机电系统控制基础课程的多参数可调实验

Multi-parameter adjustable experiment for basic course of Mechanical and Electrical System Control

研制了课程用硬件可配置、软件可编程、参数可调节、内容可扩展的实验装置,通过改变伺服系统的驱动功率、驱动力矩、转动惯量、摩擦阻力矩、传动轴刚度、减速比、采样频率、控制参数等,使学生更直观地理解机电参数、控制参数与系统数学模型的映射关系。设计了4个典型的控制实验,实验内容不仅覆盖课程所有章节,而且涵盖机械设计、自动控制元件、电子技术、驱动控制、传感器、计算机编程等多门主干课程的关键知识。通过实验教学,不仅有助于加深学生对理论知识的认识和理解,也有利于提高学生的工程综合实践能力。

An experimental device with configurable hardware, programmable software, adjustable parameters and expandable content for the course is developed. By changing the driving power, driving moment, moment of inertia, friction resistance moment, stiffness of transmission shaft, deceleration ratio, sampling frequency and control parameters of the servo system, the multi-parameters can be adjusted so that students can understand more intuitively the mapping relationship between mechanical and electrical parameters, control parameters and system mathematical model. Four typical control experiments are designed, and the experiment contents not only cover all chapters of this course, but also cover the key knowledge of mechanical design, automatic control components, electronic technology, driving control, sensors, computer programming and other main courses. Through experiment teaching, it is not only helpful to deepen students’ understanding of theoretical knowledge, but also helpful to improve their comprehensive engineering practice ability.
