摘要
为了提高大摆锤游乐设施在运行时的稳定性,同时提升游客乘坐大摆锤时的安全可靠性和舒适性,基于D-H法建立大摆锤的动力学方程,定量分析乘客位置各方向的加速度。其次,利用拉格朗日法建立了大摆锤系统的动力学方程。最后根据模糊理论设计了模糊PD控制器,提高大摆锤工作时的控制精度和稳定性,并在Matlab/Simulink中进行仿真。结果表明:所设计的控制策略能有效提高大摆锤的稳定性。
In order to improve the stability of the large pendulum ride in operation and enhance the safety,reliability and comfort of tourists riding the large pendulum,the dynamic equation of the large pendulum is established based on the D-H method to quantitatively analyze the acceleration of passengers in each direction.Secondly,the Lagrange method is used to establish the dynamic equation of the large pendulum system.Finally,according to the fuzzy theory,the fuzzy PD controller is designed to improve the control accuracy and stability of the large pendulum,and the simulation is carried out in Matlab/Simulink.The results show that the designed control strategy can effectively improve the stability of large pendulum.
