Full TextAbstract
Abstract In this paper, time-delay control systems with quadratic performance are solved by applying the least square method on the Bezier control points. The approximation process is done in two steps. First, the time interval is divided into 2k subintervals, then in each subinterval the trajectory and control functions are approximated by the Bezier curves. We havechosentheBeziercurvesaspiecewisepolynomialsofdegreen anddeterminedtheBezier curves on any subinterval by n+1 control points. By considering a least square optimization problem, the control points can be found, then the Bezier curves that approximate the action of control and trajectory can be computed as well. Some numerical examples are given to verify the efficiency of the proposed method.
