摘要

倒立摆是一种具有多变量、非线性、强耦合的典型欠驱动系统。针对一阶倒立摆控制问题，采用牛顿-欧拉法分析和建立了倒立摆数学建模。基于线性状态反馈设计了LQR控制器，研究了LQR控制器权重系数对控制性能的影响，并基于Simscape环境搭建了系统仿真模型。实验结果表明，LQR控制稳定，反应时间快，鲁棒性强。

Abstract:

Inverted pendulum is a typical underactuation system with multi-variable, nonlinear and strong coupling. Aiming at the control problem of first order inverted pendulum, the mathematical model of inverted pendulum is analyzed and established by Newton-Euler method.The LQR controller was designed based on linear state feedback, and the influence of the weight coefficient of the LQR controller on the control performance was studied. The simulation model was built based on Simscape environment. The experimental results show that the LQR control is stable, the reaction time is fast, and the robustness is strong.

Key words: first-order inverted pendulum LQR simscape simulation
