In order to overcome the difficulty of parameter setting and the bad versatility of the parameter adjustment level in the human-simulated intelligent controller
a means of fuzzily setting proportional parameters on line was presented.According to fuzzy control theory
system error and its changing rate during the dynamic response process were treated fuzzily.By utilizing the fuzzy information
the proportional parameters were modified on line.The MATLAB was used for simulation test on a second-order system with pure time delay.The results show that the second owed damping system can track step input signals without overshoot by this means.
