Optimal Tracking Control Scheme for Discrete-Time Nonlinear Systems with Approximation Errors

2013
In this paper, we aim to solve an infinite-time optimal tracking control problem for a class of discrete-time nonlinear systems using iterative adaptive dynamic programming (ADP) algorithm. When the iterative tracking control law and the iterative performance index function in each iteration cannot be accurately obtained, a new convergence analysis ...

Convergence Proof of Approximate Policy Iteration for Undiscounted Optimal Control of Discrete-Time Systems

Cognitive Computation, 2015
Approximate policy iteration (API) is studied to solve undiscounted optimal control problems in this paper. A discrete-time system with the continuous-state space and the finite-action set is considered. As approximation technique is used for the continuous-state space, approximation errors exist in the calculation and disturb the convergence of the ...

Approximate Gradient/Penalty Methods with General Discretization Schemes for Optimal Control Problems

2006
We consider an optimal control problem described by ordinary differential equations, with control and state constraints. The state equation is first discretized by a general explicit Runge-Kutta scheme and the controls are approximated by piecewise polynomial functions.

Optimal discrete approximation of continuous linear operators applicable to control problems

Kybernetika, 1985
Der Verf. untersucht Methoden zur optimalen Approximation von höheren Ableitungen. Unter Verwendung allgemeiner funktionalanalytischer Konzepte treten hier Interpolationsaufgaben mit Spline-Funktionen auf. Speziell wird der Fall der kardinalen Splines betrachtet.

Discrete-time approximation of optimal control problems for delayed equations

1996
Summary: We deal with the infinite horizon optimal control problem for a nonlinear system of differential equations with constant delay focussing our attention on its numerical approximation. Dynamic programming is used to get an approximation scheme based on the time discretization of the dynamics and of the pay-off.

Discrete optimal control with dynamic switches : outer approximation and branch-and-bound

Many real life applications lead to optimal control problems whose control is given in form of a finite set of switches. These switches can be operated within a given continuous time horizon and admit only a finite number of states. Examples include gear-switches in automotive engineering or valves and compressors in gas networks.
