二级倒立摆的状态变量合成模糊神经网络控制
杨振强,,程树康
控制与决策 , 2002,
Abstract: 为解决模糊神经网络在控制多变量系统时的规则组合爆炸问题,提出用状态变量合成模糊神经网络控制二级倒立摆。该方法既能解决具有快速、强非线性、绝对不稳定系统的控制问题,又能对状态变量可按性质和类型分类的多变量系统,大大减少模糊神经网络控制器的规则数,有利于利用专家的控制经验。实验结果证实了该方法的控制效果好,鲁棒性强。

Abstract: ?针对多输入-多输出(MIM0)非线性系统基于模糊基函数向量提出了一种新的自适应控制方法.在该方法中,首先将非线性系统线性化,然后利用模糊基函数向量自适应学习系统不确定向量的上界,模糊基函数向量可作为补偿控制器的一个参数.在控制系统的设计过程中可充分保证非线性控制系统的鲁棒性和跟踪误差的渐进收敛性.

Abstract: 针对一类连续非线性不确定系统,基于模糊逻辑提出了一种新的自适应跟踪控制方法.在此方法中,控制器由两部分组成:模糊逼近控制器(FAC)和模糊滑模补偿控制器(FSMCC).其中,FAC利用模糊逻辑系统全局逼近理想控制器,FSMCC用于全局补偿逼近误差和系统的不确定性及消除外部干扰的影响.整个闭环控制系统在Lyapunov意义下全局渐进稳定且系统的跟踪误差收敛于零的某一邻域内.最后通过示例验证了本方法的有效性.

自动化学报 , 2000,
Abstract: In this paper, a novel adaptive control approach based on fuzzy basis function vector is presented for Multi input and Multi output(MIMO) nonlinear systems. The nonlinear plant is first linearised, the fuzzy basis function vector is then introduced to adaptively learn the upper bound of the system uncertainty vector, and its output is used as the parameters of the compansator in the sense that both the robustness and the asymptotic error convergence can be obtained for the closed loop nonlinear control system.

自动化学报 , 1999,
Abstract: The paper is concerned with parametric adaptive control of continuous time chaotic systems. A new method of parametric adaptive control is presented for nonlinear chaotic systems with multi parameters. The system parameters are considered to be linear form in the adaptive control, and the Lyapunov method is used to prove that parametric control equations are globally asymptotically stable. It has been shown that the method in this paper is a very effective one to analyze parametric adaptive control for chaotic systems.

控制理论与应用 , 2001,
Abstract: On the basis of the fuzzy logic, a direct adaptive tracking control architecture is developed for a class of nonlinear dynamic systems. In the procedure, the controller is composed of fuzzy approximate controller (FAC) and fuzzy sliding mode compensating controller (FSMCC), The FAC is used to approximate the optimal controller globally, and the FSMCC is designed globally for compensating the approximation errors and uncertainties of systems, and meanwhile attenuating the external disturbance. Global asymptotic stability of the whole closed control system is obtained in the Lyapunov Sense, with tracking errors convergency to a neighborhood of zero. Simulation results demonstrate the effectiveness of the proposed algorithm.

Abstract: ?目前,电磁技术在工业。农业、国防、现代科学技术等各个领域已有了广泛的应用.在石油和石化工业部门对电磁技术的应用也很重视,并取得了可喜的成果.但是,各地区、各部门在电滋技术的应用方面发展并不平衡,有的应用效果好,有的应用效果不太好.这主要是不知道应用效果好坏的原因所在,也就是说,在应用中还存在一定的盲目性.为提高在应用中的自觉性,从理论上搞清其机理是必要的.不少人曾对磁场处理的燃料油进行了大量?...
