Fuzzy logic controller for longwall mining shield alignment
- West Virginia Univ., Morgantown, WV (United States)
At West Virginia University, we are working on an application of longwall mining methods to the problem of hazardous waste containment. This application requires stringent control of the position of each shield, including control of its orientation with respect to the face. This problem will be handled by using European style shields which include lateral hydraulic cylinders coupling adjacent shields. In Europe, this system is used to control lateral creep during face advance maneuvers. We propose to adapt the system to control shield position and orientation. We have developed a shield position control system based on the use of Fuzzy Logic which is accurate, flexible and computationally much simpler than an equivalent controller using traditional methods. The controller is of general interest because the mechanism is similar to many other common applications requiring multi-actuator control. The controller was developed by combining a formal kinematic analysis of the mechanism with computer simulation of the closed loop system. This paper describes the problem, the approach taken to the development of the fuzzy rule set and the results of the simulation studies used to test the performance of the controller.
