1. A control system for controlling a solids transport system comprising: a monitoring system in communication with the solids transport system to provide an output signal indicative of the operation of the solids transport system, the control system comprising: a hierarchical fuzzy control system operably connected to the solid transport system and comprising a plurality of fuzzy controllers, the hierarchical fuzzy control system comprising a global fuzzy controller operably connected to each of the plurality of fuzzy controllers and controlling an operation of each of the plurality of fuzzy controllers; and a flow control device in communication with the solids transport system; wherein the hierarchical fuzzy control system receives the output signal of the solids transport system, determines an input signal based on the received output signal to optimize the operation of the solids transport system, and outputs the input signal to the flow control device of the solids transport system to control at least one of an input parameter or output parameter of the operation of the solids transport system.
