Abstract : Control systems that include nonlinear devices such as limiters and relays with hysteresis are described by a set of first-order nonlinear differential equations. A Runge-Kutta integration method with special procedures to recognize discontinuities is then used to determine time responses using a digital computer. Results are presented for a nontrivial attitude-control system. Initial attempts of estimating parameters for this system using iterative minimization procedures were only partially successful. The difficulties encountered are discussed. (Author)
