This article describes an industrial control algorithm for controlling the compressed air supply to jet mills, a type of materials processing equipment. The algorithm provides for energy peak shaving and optimization of utility supply and demand. There are no infinite resource inputs to any system. The supply of utilities, e.g., electricity, steam, air, fuel, or water, to a given system or manufacturing complex is subject to maximum amount limit restrictions. Attempts to exceed the maximum limit of any single utility result in process disruption or system failure. A common example is overloading an electrical circuit. Industrial complexes include equipment or processes that make large demands on system resources or utilities.
