RLS parameter identification and emulate based on matlab/simulink

This paper based on the analysis of least-squares algorithm derived a RLS of calculation formula and proposed based on MATLAB/Simulink the use of RLS to identify the parameters of design and simulation methods.Adopt the simulation model with MATLAB /Simulink and the method using S-function in MATLAB to design the algorithm of RLS.According to an given example,the simulation and results are analyzed.The simulation results show that the method can overcome such disadvan-tages as properties of complexity,diffculty and lengthiness in the traditionalmethod of using program language.By using this method,the dynamic system simulation becomes easy,visual and quick.So it is a simple and effective method of least squares programming Simulation.
