Kalman Filter

Hi everyone, i wanna ask something about kalman filter code. in my case, this method is used for DC motor system optimization. Does anyone can help? Thank you.

that is a pretty general question; you might want to add details

[Ahmed Hakim]

search for Kalman filter in matlab exchange

and check for this link it has a KF simulink example, May be can help

okay, this is my transfer function close loop system before tuned with kalman filter.

t=0:0.01:5;
num= [0 0 0.31185 8.28 55.2];
denum=[0.001088 0.044 0.69185 9.28 55.2];
sys=tf(num,denum);
step(sys,t)
grid
title ('Unit-Step Response')
xlabel('t')
ylabel('Amplitudo')

so , how to add kalman filter to this coding ?

For MH. At you the control system of the engine on the basis of use of the filter of Kalman will turn out. It is necessary to control any parameter of the engine. The code of the program should be written further. As a result, it is necessary to use function of MATLAB [ ] = kalman(sys,Qn,Rn,Nn). Then to receive L P M Z . Then to substitute all data in the system of uroavneniye which is an optimal solution of initial system of uroavneniye for your plant_(num/denum).
