Optimal linear feedback control for non-linear-non-quadratic-non-Gaussian problems

研究成果: Conference article同行評審

摘要

An optimal linear feedback controller designed for a general nonlinear stochastic system with nonquadratic performance criteria and using a non-Gaussian approach is presented. The non-Gaussian method is developed by expressing the unknown stationary output density function as a weighted sum of the Gaussian densities with undetermined parameters. With the aid of a Gaussian-sum density, the optimal feedback gain for a control system with complete state information is derived. By assuming that the separation principle is valid, a nonlinear precomputed gain filter is then implemented. The method is illustrated by a Duffing-type control system, and the performance of a linear feedback controller designed through both quadratic and nonquadratic performance indices is compared.
