This paper presents an enhancement of nonlinear proportional-integral-derivative (PID) controller for pneumatic positioning system by utilizing the characteristic of rate variation nonlinear gain known as multi-rate nonlinear PID controller. The proposed technique is designed and implemented to a v...
