Abstract:Inverted pendulum is a nonlinear and unstable system. The control of the system is pretty complex and is applied in the aerospace, military, robots and other intelligent control area. Pendulum is the ideal platform for testing new control algorithms. This paper describes the composition and working principle of linear inverted pendulum system; Firstly, according to the physical model of the linear inverted pendulum, a mathematical model is built by mechanical analysis and approximate processing. Afterwards, using the PID and Fuzzy control build reasonable simulation module in MATLAB/Simulink. Comparing stabilization control results on inverted pendulum system of different algorithms, find the best control scheme to control and analyze the characteristics of different algorithms. Lastly, the experiment of realtime control over the single inverted pendulum is given to verify the simulation results and the actual results.
