Solution of Bang-Bang Optimal Control Problems by Using Bezier Polynomials
In this paper, a new numerical method is presented for solving the optimal control problems of Bang-Bang type with free or fixed terminal time. The method is based on Bezier polynomials which are presented in any interval as $[t_0,t_f]$. The problems are reduced to a constrained problems which can be solved by using Lagrangian method. The constraints of these problems are terminal state and con...
متن کاملContact Smoothing in Sensitivity Analysis and Optimization of Multi-body Contact Problems
Sensitivity analysis (SA) is developed for 2D and 3D multi-body frictional contact problems. The direct differentiation method (DDM) is applied to obtain response sensitivities with respect to arbitrary design parameters (parameter and shape SA). The FE formulation of contact employs smoothing of the master surface, and the augmented Lagrangian technique is used to enforce the contact and frict...
متن کاملA SIMPLIFIED LAGRANGIAN MULTIPLIER APPROACH FOR FIXED HEAD SHORT-TERM HYDROTHERMAL SCHEDULING
This paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. In fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. Thepower output of each hydro unit varies with the rate of water discha...
متن کاملAugmented Lagrangian Techniques for Ellipticstate Constrained Optimal Control
We propose augmented Lagrangian methods to solve state and control constrained optimal control problems. The approachis based on the Lagrangianformulationof nonsmoothconvex optimization in Hilbert spaces developed in 6]. We investigate a linear optimal control problem with a boundary control function as in 1]. Both the equation and the constraints are augmented. The proposed methods are general...
متن کاملOptimal Control of Navier - Stokes Equations 1
In this paper we study optimal control problems of the uid ow governed by the Navier-Stokes equations. Two control problems are formulated in the case of the driven cavity and ow through a channel with sudden expansion and solved successfully using a numerical method based on the augmented Lagrangian method. Existence and rst order optimality condition of the optimal control are established. A ...
