Abstract :
A new control method of tendency surface based on cubic polynomial (TSCP) is proposed; the definition of the tendency of control output is given; the cubic polynomial correlation coefficients are determined to meet the requirements of tendency of control output. At the same time, the procedure to expand the univariate polynomial curves into surface is suggested. Further, tendency surface is optimized by genetic algorithm. Simulation results verify the effectiveness of the given method.
