A multi-variable control system for the optimisation of a ball-mill coal-pulveriser has been proposed (Zhou et al., 2003). The system is based on a three-neural decoupling control mechanism and is able to cope with long delay and strong coupling in the system. The method has been tested on a full-scale plant. 10.3.2 Fuel splitting control
