Abstract

According to research demand, a deep-sea extreme environment simulator was designed. This paper gave an analysis of system architecture principles, and expounded training vessel, temperature control system and pressure control system. Because of low pressure control accuracy for the current simulator, a high precision pressure sensor was designed and an iterative learning PID pressure control algorithm was put forward, which could automatically detect the system pressure and continuously control it. At the same time, a training vessel with two observation windows could take real-time observation of microorganism. Experiments showed that the system can control the vessel pressure accurately and simulate the deep-sea environment; it provides a good platform for deep-sea extreme environment research.
