摘要	A novel model predictive control method based on subspace identification for linear parameter varying (LPV) systems is presented. The LPV systems in innovations are introduced to derive the subspace prediction output with the subspace identification algorithm. The subspace prediction output is composed of the time-varying system matrices and the transition matrices. Next, the subspace prediction output is transformed to the appropriate one for the design of the controller. Through RQ factorization, the R matrix can be obtained from the above subspace prediction output. The subspace predictors are derived from R matrix using the orthogonal projection. Then, the subspace predictors are used to design the model predictive controller. The controller is to get the control sequence which can be obtained by minimizing the cost function and the control input is calculated from the control sequence. It’s shown that the integrated action is incorporated in the control effect to eliminate the steady error. The simulation example is a model of the out-of-plane dynamics of a flexible rotor blade of a fixed speed wind turbine and it can be represented as the LPV system state-space model. The simulation results are provided to illustrate the performance of this method. © 2016, North Atlantic University Union. All rights reserved.
