IEEE Transactions on Cybernetics, 2023
In this article, we investigate the lag consensus and lag $\mathcal {H}_{\infty }$ consensus problems for second-order nonlinear multiagent systems (MASs) by utilizing the proportional-derivative (PD) and proportional-integral (PI) control methods.

Generalized PI controllability
International Journal of Control, 1996Integral controllable systems can be stabilized by all sufficiently low-gain integral controllers. The concept of integral controllability is extended to two generalized stability regions and to proportional controllability and PI controllability with respect to those regions.

A Predictive Proportional + Integral (PPI) controller with improved performance over standard PI and PID controllers is proposed. This controller consists of two parts: a standard PI controller and a predictive term with which its dynamics depend on the system time delay. The controller is realized by a continuous time implementation; i.e.

Position Control with 2DOF PI Controller
2020 21th International Carpathian Control Conference (ICCC), 2020This paper is dealing with an application of two degrees of freedom controller (2DOF) on position control. The focus is to apply optimal weight of the 2DOF PI controllers on real model to improve quality of control process and reduce overshoot. The achieved results on the real model are compared with simulation.
