An Intelligent Temperature Controller for Jacketed Reactors

Achieving good temperature control in multipurpose, jacketed reactors is difficult. Physical properties of the system change within a run and from run to run. Setpoints are changed often, and nonreactive, exothermic, and endothermic processes must be controlled. A microprocessor-based control system has been used to implement a control strategy that uses a mathematically simple algorithm together with the logic used by a skilled operator to achieve good control for setpoint changes and reactions in a multipurpose system.
