Optimal Preview Repetitive Control Of Linear Discrete-time Systems

Nowadays,the rapid development of social informatization.At present,the hot spot at home and abroad is to process signals and data from multiple sources.Information fusion is the big data analysis of data and signals from different sensors under predetermined rules in computer technology.Through the fusion of foresight control technology can make the existing future information into the control system,and thus overcome some of the basic information cycle delay problems faced by the repeated control system,thereby correcting the tracking effect of the control system,while relying on the existing foreseeing control technology and the repeated control system research,this paper will foresee the control technology and the repeated control system research integration,with the discrete system as the main research goal,put forward the design scheme of the optimal foreseeable repetitive controller,and study the specific parameters based on the information fusion estimation method.Following aspects:(1)Based on information fusion,discrete systems foresee repetitive control.Repeat control is foreseen based on information fusion discrete systems.First,the L-order differential technique is used.The control strategy design problem then becomes a stability issue.The co-state is used to describe the process of optimal fusion,resulting in optimal estimated filtering.Finally,all the information about the control law is fused to obtain a foreseeable repeat controller.(2)Nonlinear discrete-time system,information fusion optimally foresees repetitive control.Discusses a class of Lipschitz discrete systems and develops predictive repetitive control strategies.By applying the differential median theorem,the difficulty of processing differences by nonlinear vector functions is solved.Further,the specific parameters of the controller are solved by information fusion estimation,and a robust repeat controller containing the foreseeable feed-forward compensation is obtained.(3)Optimal predictive repetitive control of information fusion with time-delay states in nonlinear discrete systems.Based on the above discrete system,a repetitive controller mainly mentioned in this paper is obtained.The way of using information fusion estimation.The median theorem and the properties of the difference operator are used to output error information and target information and repeat controller into the fusion augmentation system,and then,estimation data volume scheme is used to solve the optimal estimate of the co-state of the control increment and the augmented error system respectively.Finally,through a series of formulas,the controller that can best keep the system in a stable state is obtained.
