把鲁棒预测控问题转化为线性矩阵不等式来求解(Solving the problem of robust predictive control into a linear matrix inequality)

qrd_rls_AR_pred.m - use the QR decomposition-based RLS algorithm to predict complex-valued AR process.(qrd_rls_AR_pred.m- use the QR decomposition-based RLS algorithm to predict complex-valued AR process.)

说明：  function [ret,x0,str,ts,xts]=smg(t,x,u,flag) smg is the M-file description of the SIMULINK system named smg. The block-diagram can be displayed by typing: smg. SYS=smg(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.
