Main Steam

The main steam pressure control system in marine steam power plant has the characteristics of time-varying, nonlinear and strong coupling. In order to get satisfactory control effect, we propose a fuzzy immune PID controller with which we can make comprehensive utilization of advantages of artificial immune, PID and fuzzy controller. We build up mathematical model of main steam pressure control system, carry out simulation and comparison. The results prove that fuzzy immune PID controller can significantly reduce the overshoot and settling time of main steam pressure. It is more effective in main steam pressure control system than PID controller.

Pressure Control System

A kind of digital pressure control project is put forward to solve the problem of pressure fluctuation inside the carriage by using the experience of airplane's pressure control system. Based on the pressure difference monitored between the inside and outside of the carriage, the control signal is output to the actuator by the controller, according to the control program set in it, in order to stabilize the pressure in the carriage. After the mathematical models of the main parts of the control system are found, a mathematical model of the whole system is established. Fuzzy control technology is applied in the new control system. The fuzzy controller is designed by using the matlab software, and then the simulation system is constructed. It is proved practical by the simulation result.

Effective Life

At cementing of casing of oil and gas wells during the process of injecting of cement slurry in the casing column the slurry can move with a higher speed than it’s linear injection speed. A break of continuity of fluid flow occurs, what can lead to poor quality isolation of producing formations and shorten the effective life of the well. We need to find some technical solution to stabilize the linear velocity of the cement slurry in the column. This task can be resolved with an automated control system.

Pressure Control System

This article introduces a measurement system based on LabVIEW used for optical interference fringe on micro-fluidic chips. This system mainly uses cameras to capture real-time images of wedge interference fringe on micro-fluidic chips, then the collected images will be binarized by LabVIEW. The processed images will be divided by zone , determine the flatness and gap thickness of the micro-fluidic chips by interference fringes with different directions of deflection and numbers. Finally, feedback from measured data will be used to adjust the flatness and gap thickness of micro-fluidic chips in order to meet the requirement of tests.

Varying Delay

The air compressor system is a time-varying, delay and nonlinear complex system, it has a very important sense to ensure that the supply pressure is stable in the compressor control system. According to the working characteristic of air compressor system, the fuzzy control theory, as one of the modern control theories, was applied into the constant pressure control system to design a fuzzy pressure controller. The simulation results show that the controller was more convenient and effective; it has certain directive significance and reference for the other parameter’s control of air compressor system.
