I want to disturbance observation simulation on matlab not on simulink.
difinition:
E:error, R:reference, D:disturbance, De:estimated disturbance
P:real plant, Pm:model of P, C:controler, F:filter,
Y:output of P, Ym:output of Pm, U:output of C
four equations:
U=C*E=C*(R-Y)
Y=P*(U+D-De)
Ym=Pm*(U-De)
De=Pm^(-1)*F*(Y-Ym)
So, when I set R and D, how can I get Y without using simulink ??
I must solve these simultaneous equations??
Or I can use somethig useful matlab functions ??

If have the a license for the Control System Toolbox you can use the connect function to build the model you want from a block diagram with R and D as inputs and Y as an output.
