It will be widely applied to engineering . a switched - mode dc / dc converter is a high non - linear control system , which has intrinsic non - linear . under certain conditions , the converter may have seemingly random chaos without repetition 开关式dc dc变换器是一个强非线性控制系统,由于其固有的非线性,变换器在满足一定的条件下,会产生貌似无规永不重复的混沌现象。
4 ) by using the famous bode integrals and the derived relations between information rates and h entropy , performance limits of several kinds of linear control systems disturbed by stationary noises are investigated from the viewpoint of information theory 4 )从信息论的角度考察控制系统性能的内在局限。结合bode积分、信息率和h 。嫡的关系,阐述了几类受随机干扰线性控制系统的性能极限。
Power electronic exhibits a wealth of nonlinear phenomena . a switched - mode dc / dc converter is a high non - linear control system , which has intrinsic non - linear . under certain conditions , the converter may have seemingly random chaos without repetition , such as bifurcation and chaos Dc / dc变换器即是一个非线性控制系统,由于其固有的非线性,变换器在满足一定的条件下会表现出丰富的非线性现象,例如分岔、混沌等。
Basing on the voltage and flux linkage equations of the induction manchine with compound cage rotor , the state space model of the motor is got . if the state equations are considered as news model and the output equations are considered as observation equations , the equations to describe non - linear controled system can be got 从复合笼条转子感应电动机的电压方程和磁链方程出发,推导出了复合笼条转子感应电动机的状态空间模型,以此状态方程为消息模型、电机的输出方程为观测方程,得到了一个描述电机系统的非线性受控系统方程。
Secondly , we introduce the theory that flat systems , an important subclass of nonlinear systems introduced via differential algebraic methods , are defined in a infinite dimensional differential geometrical framework . utilizing this method , the control system of the vtol aircraft becomes a linear control system . finally , we introduce the theory that is found by my teacher , wanghong professor 3 、应用平坦性分析方法和整体微分几何方法分别分析了pvtol飞机在其起飞过程时的控制律,得到了该系统的整体化方程,指出了该系统是能控能观的,并且指出该系统是平坦的控制系统,可以通过动态状态反馈和适当的坐标变换使之变成线性系统。
