To avoid superheater steam temperature of supercritical boiler effect such as presumably higher or lower by disturbance,this paper proposed an adaptive dynamic matrix control(DMC) algorithm based on the theory which combining DMC with discount recursive partial least squares(DRPLS).

To overcome the large memory expense in the process of on-line identification by utilizing support vector machine(SVM), least squares support vector machine (LS-SVM) was combined with recursive least square(RLS), the weigh vector and bias were adjusted on-line by RLS algorithm, and on-line identification of inverse dynamic model of system was realized.

The recursive least square can regulate the Q and R matrix dynamicly and rapidly.

Firstly,the method establishes a heat balance model through modifying the parameter of academic reac- tion heat balance expressions using the recursive least square method.

Application of RLS in warning controller;

RLS parameter identification and emulate based on matlab/simulink;

Its parameters are identified with the Recursive Least Square method(RLS).

By analyzing the several situations of the vehicle movement,using the recursive least squares method and the generalized least square error method,an adaptive controller of vehicle s acceleration was designed.

Then,the coefficients of consequent components in T-S fuzzy logic controller were to be determined with recursive least square algorithm for the empirical data while the membership function parameters of input variable were unaltered.
