Some Improvements to the Algorithm of Self-tuning Regulator

In this paper,some improvements is given to the algorithm of self-tuning regulator.First,an approximation algorithm for self-tuning regulator is suggested.Tocompare with the normal algorithm,this one has following advantages:better precision,less memory space,and less computing time.A method to restrain matrix p(t) in parameter estimation of a self-tuning regulator is given.The fact that themethod may avoid the blow-up of the matrix p(t) effectivery is shown by the simulation.
