Hybrid computer solutions for optimal control of time-varying systems with parameter uncertainties

Published: 17 November 1970 Publication History

Abstract

A hybrid computing scheme is described which economically solves optimal regulator problems for time-varying systems. The variational problem of determining optimal time-varying controller gain schedules is reduced to a sequence of standard one-dimensional parameter searches and high-speed simulations by restricting the class of optimal gain schedules to be piecewise linear.
