In this paper, an optimal gain tuning method for PID controllers is proposed using a novel
combination of a simplified Ant Colony Optimization algorithm and Nelder–Mead method …

In practical applications, the pure derivative action is never used, due to the “derivative kick”
produced in the control signal for a step input, and to the undesirable noise amplification. It …

A proportional-integral-derivative (PID) controller is a generic feedback controller widely
used in industrial control systems, process control, motor drive, and instrumentation. Despite …
