9 Design Case Studies
9-52
This is done by
% Note: set sample time to –1 to mark model as discrete
Plant = ss(A,[B B],C,0,–1,'inputname',{'u' 'w'},...
'outputname','y');
Assuming that , you can now design the discrete Kalman filter by
Q = 1; R = 1;
[kalmf,L,P,M] = kalman(Plant,Q,R);
This returns a state-space model kalmf of the filter as well as the innovation
gain
M
M =
3.7980e–01
8.1732e–02
–2.5704e–01
The inputs of kalmf are and , and its outputs are the plant output and
state estimates and .
