The output of the controller was modified to control, the closed loop performance.
Significantly reduced number of rules compared to other FLCs [10-12] .
The proposed scheme is demonstrated on different second order models with variable dead time and also its effectiveness is tested on a practical overhead crane set -up.
Adaptive Fuzzy PD Controller - AFPDC
The output SF of FLC needs to be determined very carefully as it has strong influence on the close -loop performance. Here, a non - fuzzy adaptive scheme is implemented for FPDC, where a real time gain updating factor β continuously adjusts the output SF.
