Implementation of Dynamic Matrix Control Algorithm Using a Microcontroller with Fixed-Point Arithmetic
AbstractThe aim of this paper is to describe software implementation of the Dynamic Matrix Control (DMC) algorithm using a microcontroller with �xed-point arithmetic. A 32-bit RISC ARM platform is used, which is cheap, but quite a powerful hardware system. To prevent register over- ow and drastic loss of precision, a partial shifting of values technique is performed. The DMC algorithm with �xed-point arithmetic is applied to a laboratory thermal process and the obtained results are compared with those of the DMC algorithm implemented in oating-point arithmetic
