Design of Virtual Simulation Experiment Teaching Project of Linear Inverted Pendulum Control System

In order to solve the problem that students cannot fully grasp the analysis and design methods of the engineering physical control system without the automatic control comprehensive experimental device in the laboratory, the virtual simulation experiment teaching design of the linear inverted pendulum control system is carried out by taking the linear first-stage inverted pendulum and the linear second-stage inverted pendulum as examples. Three-dimensional animation technology, visualization technology, computer programming technology and database technology are used to provide students with virtual simulation experiment training on the structure and disassembly of linear inverted pendulum system, as well as photoelectric encoder principle, modeling of linear inverted pendulum system, single loop PID control, double closed-loop PID control, state feedback control and LQR control. Adopting a student-centered teaching approach, and through the self-interactive virtual simulation experiment, the students master the classical nonlinear system modeling, analysis and controller design methods, and the teaching effect of “With the virtual to fill the real, deep interaction, integration of theory and practice ” is achieved.
