- Secondly , the reliable hx control problem of uncertain nonlinear systems with strictly redundant control elements is studied in detail . based on hji . the reliable state feedback controller and output feedback controller are presented . by considering a class of nonlinear time - varying uncertain systems with time - delay and unknown nonlinear disturbances , the linear memoryless dynamic output feedback controller based on a state observer is designed such that , for all admissible uncerntainties as well as actuator failures occurring among a prescribed subset of actuators , the closed - loop system is quadratically stable with an ha norm bound constraint
考虑到时间延迟问题广泛存在于实际系统中，因此，针对一类时滞不确定非线性系统，考虑系统的状态是不可测或者是不完全可测的，设计了基于状态观测器的线性无记忆观测状态反馈控制器，使得故障闭环系统对于任何容许的不确定性和给定执行器集合中任意执行器失效是二次稳定的且对于系统扰动h _范数有界。 - The fluctuation of active power , ( pe ) , is used as the measurable key disturbance for destroying stability of generator . at the same time , the nonlinear problem of generator equation will be avoided when the measurable disturbance is used as a feedback in the controller
同步发电机输出有功功率的波动p _ e是危害发电机稳定性的主要因素， p _ e的不确定性具有扰动的本质特性，以p _ e作为可测的反馈扰动变量，将避免发电机方程非线性的难题，并能够简化控制器的设计。 - Further - more , by constructing the relations between the fiflite subshift on the symbolic set and the chaotic iterated map by means of marotto theorem , we investigate the structure of the invariant as well as the estimation of topological entropy , zeta - - function , lyapunov exponent . by the end of the chapter , we present several conclusions on the perturbed chaotic systems and a theorem about " heteroclinical repellers imply chaos " . in chapter 3 , we are mathematically modelling two particular classes of impul - sive differential equations having chaos dynamics
在本文的第三章中，我们建立了脉冲微分方程中的两类混沌模型，一类利用映射的扰动理论证明了系统随着参数变化时具有不同意义的混沌动力学行为；另一类则利用勒贝格可测的概念给出了脉冲微分方程中所特有的关于脉冲间期函数初值敏感的定义，同时理论证明了在一类脉冲微分方程中确实如新定义所描述的复杂动力学行为 - The rotor velocity and position can be taken as two states variable of the system by using the ekf on the basis of the theory of the bldcm . based on the measured stator currents and stator voltages , we can estimate the rotor velocity and position . it is very useful for us to study the application of the velocity and position sensorless operation of brushless dc motor drives
在直流无刷电机的原理基础上,利用扩展卡尔曼滤波器将转子转速和位置看成系统的两个状态变量,根据定子侧可测的电流、电压值,逐步估计出转子转速和位置,为无速度和位置传感器无刷直流电机控制系统打下基础。
