This letter describes work currently being carried out in the field of adaptive optimally switched control systems using digital techniques. Basically the actual phase-plane trajectory of a second-order system is compared with the optimum trajectory, to obtain the correct switching point for minimum response time. A novel method is used to avoid measurement or computation of error rate, and some conclusions are given.
