GAIN 값 변화에 강인하게 개선된 PID 제어기

A Robustly Improved PID Controller at Change of Gain Value

Up to now, PID(Proportional Integration Derivation) controller for industrial motion algorithm is commonly used. However, there are largely two shortcomings which are derivative kick and having a difficulty choosing each gain value for system control. In this paper, we propose an improved robust PID controller at change of gain values. By using it for DC Motor speed optimal control, SD(standard deviation) of its performances for system stability via overshoot, settling time, rising time, steady-state error is discussed. additionally, in case of comparing our proposed PID controller with conventional one, the former has a more effect on system stability than the latter. Matlab simulation is used for each identification.
