Developing of optimal control system for UCG

Underground Coal Gasification (UCG) belongs to clean technologies for obtaining energy from coal seam. Optimal control of UCG is one way for increasing of effectiveness the transformation coal to syngas. Process control system has been developed in UCG laboratory. Feedback optimal control was developed as system with two levels. Basic level is stabilization and upper level is optimization. Optimal control system is based on using of gradient method. There will be analyzed optimal control for three input control variables for various types of functional.
