【Abstract】 The dry cleaning of coal with air dense medium fluidized bed (ADMFB) is a cleaning technique of coal with great economic value. The key equipment is an ADMFB separating machine. In this paper, the technical process of dry cleaning of coal with ADMFB and multivariable nonlinear system model were simply presented. The pole allocation controller of control system based on inverted system method was designed. Finally, the practical control result and analysis of bed high and density were discussed.更多还原
