Chebyshev series approach to system identification, analysis and optimal control. (English) Zbl 0538.93013
Various orthogonal functions (e.g. Walsh, block-pulse and Laguerre functions) are now widely used in identification, analysis and design of control systems. In this paper the author makes use of the Chebyshev series for estimation of system’s parameters and initial states as well as for solving the state equations and computing the optimal control in linear-quadratic time-invariant problems. The algorithms derived are similar to those based on other orthogonal functions but have some advantages. This is due to the fact that Chebyshev series permit almost uniform least squares approximation and a more exact representation of multiple integrals.
