针对结构振动控制仿真分析中存在编程工作量大等问题 ,提出在Simulink中建立线性结构和非线性结构的动力模型 ,给出了基于C ++和MATLAB的Simulink软件包及其扩展工具S函数的解决方法 ,并且以线性最优控制算法驱动的MR阻尼器为例 ,说明了在Simulink中建立控制算法模块和控制器模块的方法 ,结果表明 ,所采用的方法亦可推广至非线性结构的控制 ,可以避免大部分繁琐的编程工作 . In order to solve the problem of large programming workload in simulation analysis of structure vibration control, a dynamic model of linear structure and nonlinear structure in Simulink is proposed. The Simulink package based on C ++ and MATLAB and its S function Solution and the MR Damper driven by the linear optimal control algorithm as an example, the method of establishing the control algorithm module and the controller module in Simulink is described. The results show that the proposed method can also be extended to the control of nonlinear structure , You can avoid most of the cumbersome programming.
