Distillation Column – MIMO System
Non-Technical Report Summary
1. A System with 2 Inputs and 2 Outputs
For this system, edeX presented a significant improvement in settling time and noise attenuation versus the PID. The settling time for edeX fuzzy logic controller (FLC) was 35% to 44% faster and the noise impact in the controller output signal was 60% to 90% smaller.
2. System with 3 Inputs and 3 Outputs
For the 3×3 system, the settling time and response to disturbance from edeX FLC was significantly better than the PID. For edeX FLC the settling time for the controllers was 48% to 90% faster than the PID. edeX FLC was able to handle disturbance issues without affecting the process.
This also means that as the complexity of the process increases, edeX FLC outperforms the PID by a greater margin.
To show the power and robustness of the fuzzy controller, we applied very large disturbances – equal to the set points. We applied these disturbances at the process output.
As can be see above, the fuzzy controller was able handle the disturbances remarkably well. Furthermore, it was able to reduce the interaction between the two loops to a minimum.
