✦ Synopsis
The paper deals with a feedback system created by the use of the method of regular synthesis of an optimal control system which should bring a non-linear and discontinuous planar object to a moving target in minimum time. In real, practical circumstances perturbations such as unexpected and undefined motion resistance variations, parameter changes and errors in measurements of states impinge on this system, which may cause the created time-optimal closed-loop system to generate limit-cycles and be stopped in a state other than the required final one. It is shown that while using the so-called ~:-solution of the discontinuous differential equation, the synthesized closedloop system may become insensitive towards the above perturbations. Some suggestions are made as to practical applications.
