On a generalization of the PI-controller
Proceedings of 32nd IEEE Conference on Decision and Control, 2002PI-controllers are known to achieve output regulation on a constant signal, in spite of sufficiently small but otherwise arbitrary linear plant perturbations. The structure of this controller is rather simple and, in view of the internal model principle, it implements the minimum dynamic extension required to achieve structural stability.

Robust PI control of hysteretic systems
2008 47th IEEE Conference on Decision and Control, 2008Stability, tracking and the trajectories of a class of hysteretic systems controlled by a PI controller is considered. The system output (not its derivative) is measured and controlled. Only a simple bound on the controller gain parameter is assumed. The closed-loop system is BIBO-stable with a finite gain of one. Furthermore, provided that the desired

Noise filtering in PI and PID Control
2013 American Control Conference, 2013Control design is a rich problem which requires a compromise between performance and robustness. This paper explores how filtering of the measured signal influences the undesirable control actions generated by measurement noise, the load disturbance response, and the robustness to process uncertainty. The analysis is condensed to design rules.

Computation of stabilizing PI and PID controllers
Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004In this paper, a simple method for the calculation of stabilizing PI controllers is given. The proposed method is based on plotting the stability boundary locus in the (k/sub p/, k/sub i/)-plane and then computing stabilizing values of the parameters of a PI controller. The technique presented does not require sweeping over the parameters and also does

Multiobjective design of PI controllers with applications
2016 IEEE Conference on Control Applications (CCA), 2016In this paper we consider the proportional-integral (PI) controller and the problem of modern design using gain margin, phase margin and bandwidth as simultaneous specifications. We develop analytical approaches to deal with these specifications leading to the generation of a design surface which displays all achievable designs as well as the various ...

The Smooth Switching of Fuzzy-PI Control
2009 Sixth International Conference on Fuzzy Systems and Knowledge Discovery, 2009Various methods of multimode control are adopted more and more widely to improve the performance of control systems. The problem of smooth switching of different controllers is the key in application of multimode control. This paper focuses on the unsteady problem at switching point of controllers in multimode control system.

Educational Issues of PI-PID Controllers
IFAC Proceedings Volumes, 2012Abstract Educational issues of Proportional, Integral (PI) and Proportional, Integral, and Derivative (PID) type controller design in undergraduate course on control, graduate course on control, advanced control topics are discussed. The main attention is devoted to multi-time-scale control systems where PI PID type controllers designed for nonlinear

Self-tuning PI control for a boiler control system
2013 IEEE 18th Conference on Emerging Technologies & Factory Automation (ETFA), 2013This paper proposes a new design method for a drum boiler system, which is a benchmark problem for PID control. The boiler is a multi-input multi-output (MIMO) system with interference, but it is divided into independent single-input single-output (SISO) systems.

Robust decoupling PI controllers for multi-loop control
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012Very often, the control of multivariable industrial processes is performed using multi-loop architectures, in which several SISO PI or PID controllers are committed to control different channels of the plant. A difficulty with such a strategy arises due to the interaction between the different control loops, which may cause the control action in a loop

PI control synthesis for event-triggered control systems
at - Automatisierungstechnik, 2015Abstract Event-triggered control aims at reducing the resource utilization, especially the communication over the feedback link, while guaranteeing a certain control performance. Although setpoint tracking problems are common in practice, the majority of the proposed approaches in literature focus on regulation problems.
