This paper proposes an adaptive time optimal control algorithm for ship steering in course changes. Dynamics of the ship are presented by a third order differential equation model. The time optimal control law is obtained by applying the Successive Order Hightening Method. It is combined with a least squares type parameter estimation algorithm to obtain the adaptive time optimal controller. The proposed control scheme is evaluated by a computer simulation study.

Abstract This article presents the time optimal control system adopted to control double winding VCM motor. This kind of control is widely used in hard disk drive servo for head positioning. Mathematical model of double winding VCM motor is presented, and its implementation in MATLAB/Simulink is shown. The extended time optimal control algorithm is implemented on dSpace DS1104 board. The results obtained from simulation and real measurements are compared and discussed
