Computational Solution To a Class of Optimization Problems.
Abstract
Optimum control problems typically involve the minimization with respect to a control input of a performance index subject to a vector differential equation describing the propagation in time of the system states. Application of Pontryagin's Minimum Principle results in necessary conditions which the minimizing control must satisfy. Unfortunately, these necessary conditions are expressed as a two-point boundary-value problem (TPBVP) which must be solved for the optimum control. Many TPBVP's cannot be solved analytically; hence, some approximate numerical scheme is necessary. Thus computational solutions occupy a central role in optimum systems control. In some optimization problems, the control which may be applied is constrained. Such constraints may be expressed as in inequality when the allowable control must, for example, be less than some maximum amount. Or such constraints may be expressed by an equality. This report examines the computational solution to the TPBVP which results when the allowable control is constrained to be either zero or one.
