Level Control in Coupled Tank System Using PID-Fuzzy Tuner Controller

This research proposes fluid level control in coupled tank system using PID controller supported with Fuzzy Logic as tuner parameter of Kp, Ki, and Kd. This is done because the PID controller has a weakness in determining the appropriate combination of PID parameters for good system performance. From the test results, obtained Kp 0-60; Ki 0-2; Kd 5-10; The analysis shows that the PID-Fuzzy tuner controller performs well, with time constants of 0.6 seconds and 0.64 seconds in tanks 1 and 2 with steady-state error-0.002 m and 0.0014 m in tanks 1 and 2.
