overshoot in Ziegler-Nichol tuned PIDs (ZNPID), their performance is usually not acceptable
for applications where small error tolerance band and precise control is required. To
overcome this problem, we propose the gain updating method called as Augmented Ziegler-
Nichols PID (AZNPID). We proposed an algorithm, which uses fourth order Runge-Kutta
method to solve differential equations involved in PID, which eventually improves the peak …
