Measurement error at step k in case for nw 1 and Xj eR 0 Problem definition Using the uncertain plant model Pu given as 9 using 10 and the a priori measured turbulence data Wk j k satisfying 13 the addressed problem . GA problem exploiting the a priori measured turbulence data is defined below. Considering that the turbulence are measured for N steps ahead the horizon step number in MPC which denotes the step number during which control performance is to be optimized is also set N. For i-th plant model PU the performance index for turbulence suppression . GA performance is defined as N-1 X Ji x Av z V X TQX Avir . .RAvk - k zi iJ TSzi 16 J k 1 k x k j 1 k k k k j k 1 k j k k k j 0 where matrices Q and S are appropriately defined positive semidefinite matrices matrix R is an appropriately defined positive definite matrix X k-jk denotes the i-th plant s augmented state at step k j predicted at step k AVk j k denotes the control input command deviation at step k j created at step k and z k j k denotes the performance output at step k j predicted at step k. There usually exist preferable or prohibitive regions for the state the performance output and the control input command deviation. For the consideration of these regions constraints for the augmented state x1 the control input command deviation Av and the performance output zi are introduced. That is they should satisfy the following constraints. Tmin Xk j 1 k Tmax j 0 N - 1 17 min AVk j k max j 0 N - 1 18 min z k j k max j 0 N - 1 19 where 7min Tmax e Rn nud min max e Rnu and min fmax e Rnz are given constant vectors. If the worst performance of Ji x1 Av z1 i d d is minimized then all the other performance of Ji X1 Av z1 is no more than the worst that is all the possible plant models PU have no more worse performance than the worst. Considering this the design objective is to 350 Advanced Model Predictive Control obtain Avk jk which minimizes the .
