Temperature control has direct effect on mouth feel of fruit and vegetable processing products. This paper, by analyzing the control requirements of cucumber slices processing water temperature, proposes to control the water temperature for cucumber slice processing production line by using fuzzy immune PID. With the features of time-varying, nonlinear and hysteretic nature for temperature control, this paper designs fuzzy immune PID controller by borrowing the regulating action of immune system and linking the advantages of immune PID controller.

This paper presents a design of PID controller for furnace temperature control system with disturbance. Currently, PID controller has been used to operate in electric furnace temperature control system because its structure is simpler compared to others. However, the issue of tuning and designing PID controller adaptively and efficiently is still open. This paper presents an improved PID controller efficiency from tuning by Nelder Mead method. The parameters of PID controller shall be obtained from the Nelder Mead optimization procedure. Errors between desired magnitude response and actual magnitude response are calculated by using the Integral of Absolute Error (IAE). The proposed Nelder Mead based PID design method is simpler, more efficient and effective than the existing traditional methods included Ziegler Nichols, Cohen-Coon and Direct Synthesis. Simulation result shows that the performance of PID controller using this proposed method is better than traditional methods and resistant to disturbance.

In this paper, taking integrated process and control platform as the background , did the research on mathematical model of boiler liner and parameters on the performance of the control system. First, created a mathematical model of the temperature of the boiler liner. Second, selected the PID controller to control the temperature control system in the case of the PID controller parameters remained unchanged. Finally, changed the boiler parameters, analyzed and compared the simulation waveforms of different boiler parameters in order to get the conclusion that different parameters had different influence on the static stability of the temperature control system and the temperature control system had anti-jamming capability.

Instability Problem

In this research, the controller was implemented in water temperature control system. This system has delay and saturation effect that caused instability problem in system. One of the effects occurred was windup effect. So, the implementation of controller needs to add anti-windup system. This paper described the comparison between 2 methods of controller design, conventional PID method and PID with Anti-Windup method.  The conventional PID method resulted the system that was hardly to achieve the steady state condition. This was caused by windup effect as the system get saturation. The integrator part in PID will get bigger. The solution to fix this instability problem was by using the PID with Anti-Windup. The result of experiment showed that the output response from the control system with the anti-windup PID has a more stable than that of the conventional PID
