次最优控制 meaning in Chinese
suboptimal control
Examples
- Numerical solutions of lq control for time - varying systems via symplectic conservative perturbation
线性时变系统二次最优控制问题的保辛近似求解 - In chapter 5 , considering an ac / dc system that includes two dc lines . based on feedback linearization in the nonlinear systems and linear quadratic optimization control theory in the linear system , two new nonlinear additional controllers are designed in the same time
第五章针对包含两条直流传输线路的交直流互联系统，采用状态反馈精确线性化方法与线性系统的二次最优控制相结合的方法，同时设计了两条直流线路的非线性附加控制器。 - The method of fuzzy modeling can be taken as a good candidate of this problem in this thesis , the inverted - pendulum system is firstly analyzed by using t - s fuzzy model due to its property of arbitrary approximation for the non - linearity . based on the parameters identification , simulations of system are made by using fuzzy logic toolbox of matlab . the results of comparison with lq approach show the performance improvement in the aspects of overshoot and fast response
本文首先利用模糊模型的非线性逼近能力，采用t - s模糊模型对小车-倒摆控制系统分析并实现了该系统的模糊建模及模糊模型各部分参数的辩识，在matlab仿真环境下借助其模糊逻辑工具箱进行了系统的仿真，与采用线性二次最优控制的系统仿真结果进行比较，改善了系统超调量及快速响应性。
