This article presents an adaptive rationalized Haar function approximation method to solve dynamic optimization with mixed-integer and discontinuous controls. Three measures are taken deal the discontinuity. First, problem is converted into a multi-stage by non-uniform control vector parameterization. Secondly, strategy proposed regulate interval division order of vectors. Thirdly, structure detection presented refine subintervals, in which adjacent arcs same input type merged one modify...
Aiming at the swing problem of container cranes in process loading and unloading cargo, an adaptive neural fuzzy (ANFIS) control method based on Takagi-Sugeno (T-S) model is proposed this paper. Firstly, mathematical crane trolley-hoist system was established Lagrange's equation. Secondly, improved T-S network proposed. Since SNPRP conjugate gradient has sufficient descent global convergence under strong search conditions. In paper, used to train premise parameters consequent model. order...
Because of the mechanism complexity, coupling, and time‐space characteristic alkali‐surfactant‐polymer (ASP) flooding, common methods are very hard to be implemented directly. In this paper, an iterative dynamic programming (IDP) based on a biorthogonal spatial‐temporal Wiener modeling method is developed solve enhanced oil recovery for ASP flooding. At first, comprehensive model flooding introduced. Then presented build relation between inputs states, in which expanded set spatial basis...
An approximate dynamic programming algorithm based on an actor–critic framework is proposed in this article. This takes the as basic framework, which actor and critic are used to optimal value function control strategy, respectively. At first, linear basis approximator function. Then method of construction system characteristics introduced. Furthermore, since injection concentration ASP flooding has a fixed interval, action weighting adopted restrict action. The parameter two strategy...
Severe weather conditions such as rain and snow often reduce the visual perception quality of video image system, traditional methods deraining desnowing usually rarely consider adaptive parameters.In order to enhance effect desnowing, this paper proposes a algorithm based on tolerance dual-tree complex wavelet.This can be widely used in security surveillance, military defense, biological monitoring, remote sensing other fields.First, introduces main work method for dynamic scenes.Second,...
