Development of Embedded Temperature Regulator Based on DMC Fast Algorithm

Abstract

A fast Dynamic Matrix Control (DMC) algorithm is proposed to satisfy the requirements of the embedded temperature regulator. There exists online high-dimension matrix inversion in the DMC control algorithm, so it is difficult to apply to the embedded temperature regulator with limited computing capacity. In this work, the high-dimension matrix is decomposed into the product of a triangular matrix and its transpose matrix by Cholesky decomposition, and the inversion of the matrix calculation could be calculated recursively. Based on the proposed algorithm, an embedded temperature regulator has been developed. Therefore, the computation cost of the fast algorithm is greatly reduced compared to the traditional DMC algorithm. The experimental results have verified that the algorithm can be applied to the embedded temperature regulator and provides better regulation effect than that with the PID control algorithm.
