Experimental Study on Real-Time Control System Testing

This paper presents an experimental study on the testing of process control for a real-time control system. Several indexes, such as the capability of system approximation output, the ramp rates, the smoothness and stability of output ability, control of temperature overshoot, are selected as performance parameters, with which validating, analyzing and monitoring the thermal performance of thermal cyclers. A testing prototype is designed and fabricated as a supplementary instrument for the experimental study. A tracking temperature algorithm with feed forward and feedback control is also introduced to improve the efficiency of system performance testing by the testing prototype.
