hinf - H_infinity design of continuous-time systems

Calling Sequence

[AK,BK,CK,DK,(RCOND)] = hinf(A,B,C,D,ncon,nmeas,gamma)

Parameters

Description

[AK,BK,CK,DK,(RCOND)] = hinf(A,B,C,D,ncon,nmeas,gamma) To compute the matrices of an H-infinity (sub)optimal n-state controller


              | AK | BK |
          K = |----|----|,
              | CK | DK |
   
    

for the continuous-time system


              | A  | B1  B2  |   | A | B |
          P = |----|---------| = |---|---|,
              | C1 | D11 D12 |   | C | D | 
              | C2 | D21 D22 |
   
    

and for a given value of gamma, where B2 has column size of the number of control inputs (ncon) and C2 has row size of the number of measurements (nmeas) being provided to the controller.
