Urgent! A question about the "ltisys" command
Posted:
Jan 31, 2013 12:38 AM


As we all know that command "ltisys" normally take 5 parameters to form a SYSTEM matrix which could be used by command "psys"
However, from the explanation described in LMI Control Toolbox, the matrices A, B, C, D are intended for the plant as
Edx/dt= A*x(t) + B*u(t) y(t) = C*(x(t) + D(u(t)
In the process of building up a gain scheduling LPV controller, the plant is normally described as
P(.,p) defined as: x = A(p)*x + B1(p)*w + B2*u z = C1(p)*x + D11(p)*w + D12*u y = C2*x + D21*w + D22*u
In the case, how can form the matrices B, C and D?
By the way, the deom "misldem.m" which is supposed to provided as a demo is en empty m file in my computer. (it is located in X:\Program Files\MATLAB\R2011b\toolbox\robust\rctobsolete\lmi\ja) . Thus, I cannot get any more detail apart from the simple lines in the Toolbox User Guide.
I't urget cause I'm building up a controller for wind turbine.
Greate thanks!
