Abstract
An investigation of a Fuzzy Logic control application for cold plate regulation was initiated, and simulation results were generated. A non-linear, one-way, flow control valve was regulated using a Fuzzy Logic control methodology, and its performance was compared here to the more traditional proportional integral derivative (PID) control under a variety of different plant disturbance conditions. Sensitivity to plant parameter variations was assessed.
The Fuzzy Logic controller for the flow-control valve operates in a “bang-bang” mode. This implies simpler, lower-cost, and more reliable drives/electronics. Simulation results show that a Fuzzy Logic controller can achieve performance as good or better than that of traditional control systems.
Temperature control systems for long-duration space missions will require either improved robustness or system reconfiguration to prevent component degradation. Fuzzy Logic controllers may provide this added measure of performance, while reducing crew workload.
