“…The transfer function of a standard PID controller is generally written in the ‘parallel form’ given by Equation (2) or the ‘ideal form’ given by Equation (3)

where the Ki is the integral gain, and Kd is the differential gain. Theoretical analysis and control experiments show that a process of the conventional heating is a first order plus dead time (FOPDT) system [ 32 , 33 , 34 ], which is a highly dynamic system. The transfer function of the FODPT system is

where K is the system gain, t is the time constant, and τ is the dead time parameter.…”

Microwaves have been widely used in the treatment of different materials. However, the existing adjustable power thermostatic reactors cannot be used to analyze materials characteristics under microwave effects. In this paper, a microwave thermostatic chemical reactor for processing liquid materials is proposed, by controlling the velocity of coolant based on PLC (programmable logic controller) in different liquid under different constant electric field intensity. A nonpolar coolant (Polydimethylsiloxane), which is completely microwave transparent, is employed to cool the liquid materials. Experiments are performed to measure the liquid temperature using optical fibers, the results show that the precision of temperature control is at the range of ±0.5 °C. Compared with the adjustable power thermostatic control system, the effect of electric field changes on material properties are avoided and it also can be used to detect the properties of liquid materials and special microwave effects.

A real-time temperature control system is designed for microwave heating of a continuousflow substance. In this system, a magnetron is used as the microwave source, and its output power can be continuously adjusted though circuit design. A programmable logic controller (PLC) is used to procedure the temperature and power data as well as lead the whole control decision. The sample temperature can be controlled by regulating the output power of the magnetron though the control signal from the PLC during the heating process. The complete system is finally assembled into a user-friendly device, where the users can operate and monitor the heating process conveniently though a touch screen. A temperature-dependent material (Phosphoric acid) is used in system tests. The results show that the designed system can successfully achieve the desired temperature with an acceptable accuracy and stability. INDEX TERMS Temperature control, continuous flow, microwave heating, magnetron.

“…Furthermore, more than 90% of design failures are due to fatigue loading rather than static stress failure. The differential design was already optimized using the high Si ductile iron for static stresses by the work done by Mr. Parag Deshpande (Deshpande 2016) and Mr. Pankaj Kalan (Kalan 2016) in this project.…”
