Abstract :
A new control method by employing optimized tendency surface based on cubic polynomial (TSCP) is proposed herein. The definition of termed control output tendency is given; and the cubic polynomial correlation coefficients are determined to meet the requirements of the tendency. At the same time, the procedure to expand the univariate polynomial curves into a three dimensional surface is suggested. Furthermore, the optimization process is utilized as automatic construction procedure of the tendency surface. The effectiveness of the proposed method has been verified by simulation results of a fuzzy controller.
