Abstract
This paper describes the development of temperature controller for seedbed heating system. This system consisted of three parts; sensing part, control part that includes the PID control algorithm, and actuating part. The control part introduced a phase angle control method of TRIAC and firmware technique using one-chip microcontroller(PIC16C73). For evaluating the performance of a PID control system, the experiment results by a developed controller are compared with these obtained from a conventional controller which utilize ON-OFF control method. The experiment results show that the proposed controller has good control performance.
