要約(英語): This research proposes a controller design method for p-inputs/q-outputs multi-inputs multi-outputs (MIMO) systems which have a greater number of inputs variables than the number of output variables. Recently, data-driven controller design methods, that can directly derive control parameters from a set of closed-loop operating data under the conditions that cannot obtain physical models and/or accurate system parameters by system identification, has been received much attention. Although some data-driven controller design methods for MIMO systems with the same number of inputs/outputs have been proposed because there are many MIMO systems in industrial sites, there are few reports about the design methods for MIMO systems with p-inputs/q-outputs. In this research, a design method of a generalized minimum variance controller (GMVC) based on the principal component analysis (PCA) is proposed. In particular, obtained p number of inputs are reduced to q number of principal components by PCA. Moreover, a data-driven GMVC is designed for a system model construceted by the principal components and system outputs. The proposed method can derive good control parameters stably than a conventional method, and the method can reduce the number of adjustable parameters that must be set by an operator. The effectiveness of the proposed method is verified by simulation examples.
