Application of self-tuning polynomial controller and comparison with standard controller

Abstract

The article deals an implementation of a numerical adaptive self-tuning controller for a usage in a drying machine in a production of small amount printed circuits boards. The controller is design to use in a 8-bit microcontroller from DZ family produced by Freescale Semiconductor providing main functions – temperature measuring and control, communication with PC. That microcontroller is a main part of the dryer, but other parts (triacs and drivers) are indispensable. A dryer dynamic system is identified during a control process by a recursive least-square method. The controlling part is calculated on the basis of a dead beat control method. Of course, it is verified on a real device with surroundings which independently change temperature and air flow and it is compared with a non-adaptive controller. © 2014 North Atlantic University Union.
