The precise control of winding tension is a key technique for manufacturing strip wound prestressed dies. The principles of producing and controlling of the winding tension are discussed in this paper. Considering a set point of variable tension in a strip winding control system, the main reasons of tension fluctuating are analyzed. An integrated control strategy of compensation and fuzzy control...
Conventional Proportional Integral Derivative (PID) control is often used in present industrial field. Because the control parameters are fixed, the tuning results are difficult to meet the demands and the system is unstable or even out of control. In order to solve these problems, fuzzy control technique is presented to meet the demands of intelligent controlling. In this paper, Matlab is used to...
In robot soccer competition, it is important that the robot can identify and approach the ball quickly and accurately. This paper presents a fuzzy control method which could improve the accuracy and speed to recognize ball. The conventional robot control consists of methods for path generation and following. When a robot moves away the desired track, it must return immediately, and while doing so,...
Multi-robot systems have been widely used in various actual fields to perform specific tasks. In the robot system, path planning is a burning problem. To solve this challenging issue, we mainly study the problem of path planning between robots and robots, robots and robots systems. Three factors are taken into account in the paper: the robot autonomous model, the real-time detection of speed and the...
The prestressed dies is an important way to improve the using life of the dies. This paper mainly analyzes the linear speed control of the winding system based on fuzzy PI where the winding tension of the system is considered as a load disturbance. Based on the actual system, the mathematical model of the winding system is built in Matlab/Simulink. The fuzzy PI control method is applied to improve...
In tension control system for winding machine, motor sometime works under minus load circumstance, in which electromagnetic torque acts as drive, but its direction is opposite with the rotary direction of motor because of load torque. In this paper, the minus load circumstance of motor is analyzed, and a minus load model of tension control system for winding machine is built. A novel idea of improved...
A novel fault detection and isolation scheme for a class of nonlinear systems is presented in this paper using fuzzy adaptive observer. First, the study assumes the physical process can be described by Takagi-Sugeno (T-S) fuzzy model. In the light of the T-S fuzzy model of the plant, the fuzzy observer comprises a number of locally linear observers and the final state estimate is a fuzzy fusion of...
Various methods of multimode control are adopted more and more widely to improve the performance of control systems. The problem of smooth switching of different controllers is the key in application of multimode control. This paper focuses on the unsteady problem at switching point of controllers in multimode control system. The concept of smooth switching in process of switching is proposed. And...
With the development of electric driving systems, the synchronization control system of multiple motors has been used widely in many industry fields recently. The research on the synchronized control technique of multiple motors is getting more and more important. This paper focuses on the synchronization control strategy of multi-motor control system based on PROFIBUS fieldbus. In this paper, the...
