- Because the extension of dynamic change in weak nonlinear system is not large , the robust reliable controller designed by ldi can make the whole controlled system stable when time lag and faults exit in the system , at the same time , satisfying robust performance index of the system . next , considered that the approximation error produced by ldi , the unmodeling error produced by system , the parameter uncertainties and the external disturbances can not be ignored , a dynamic neural network controller is designed to compensate their effect on line . adjusted by the state output error between the ideal model and the controlled system , the cooperation of on - line network compensator and linear h _ ( ) controller of ideal model makes the whole close - loop system guar antee robust stability and track the specified signal well
本文在基于线性微分包含( ldi )的技术基础上，提出了两种非线性系统的鲁棒控制方法，首先讨论了一类弱非线性时滞控制系统中的鲁棒可靠控制器设计问题，由于弱非线性系统本身的动态变化范围不大，在确保整个系统鲁棒性能指标的前提下，当系统存在时滞和故障时，通过ldi设计出的鲁棒可靠控制器可以镇定整个被控系统；其次，在考虑运用ldi技术产生的逼近误差、系统本身的未建模误差及参数不确定性以及外部扰动的影响不能被忽略的情况下，设计了在线补偿这部分影响的动态神经网络控制器，在理想模型和被控系统状念输出误差的调节作用下，在线神经网络补偿器与理想模型的线性h _控制器相互配合，使得整个闭环系统既可以保证鲁棒稳定性又能够跟踪给定的指令信号。 - Secondly , the dynamic features , surplus torque and loading gradient features of ptss are analyzed by the couple model between the rudder and the eals . it can be concluded that the surplus torque is related directly to the velocity of the rudder , and the loading gradient is the disturbing inverse ratio from the surplus torque to the closed - loop model , which shows the scaling relationship between the input and the disturbance signal act on the eals . it also can be concluded that , under the same dynamic specification , it is more difficult to realize the small loading gradient
然后,采取把系统模型转化为舵机和负载模拟器相互耦合作用的形式,对被动式力矩伺服系统动态特性、多余力矩和加载梯度一一进行理论分析,得出:多余力矩与舵机运动速度直接相关;加载梯度是在系统闭环模型中,与多余力矩相关部分模型幅值大小成反比的系数,体现了被动式力矩伺服系统的指令信号和扰动信号之间的比值关系,从而在相同的动态指标下,小加载梯度实现更为困难。 - It is one of the important parts for the control of hupqc to detect the reference compensation signal . the predictive strategy is presented based on wavelet theory , that means tracing the fundamental signal and replacing with sampling data every half cycle . the fundamental signal is forecasted step - by - step in a half cycle earlier
补偿指令信号的检测是电能质量调节装置的控制环节之一，本文提出了基于小波理论的预测检测策略，跟踪基波信号，以半周期为采样更新速度，应用小波变换法对信号的基波分量进行递推式预报，并取其与实时信号之差做为参考，然后产主与之大小相等、相位相反的信号作为hupqc的实时补偿指令信号。
