Abstract

Though it is difficult to apply TOC (Time Optimal Control) law to a high-order system, it is desirable to utilize the dynamic characteristics of the TOC system for applications. To design the control system of a underwater navigator, a new method with MLSP (Multi-Linear Switch Plane) control law for designing TSOC (Time Sub-Optimal Control) system is proposed. For the linear system the MLSP control law is given. The new method proposed has the following advantages: 1. The MLSP control approaches the TOC law, and the approach becomes better as the number of linear switch planes selected freely by designer increases; 2. Since the switch surface is composed of multi-linear planes, the control law is easily implemented. The simulation results for depth control system of a underwater navigator confirms the validity of this method.
