Modifications of PID regulators
Automation and Remote Control, 2010We present a survey of the different kinds of PID regulators that have found applications in industrial automation. We present their advantages and disadvantages.

Design of Discrete PID Regulators
2018In a sampled-data control circuit the regulator can be designed in the frequency domain taking into account that by sampling and applying a zero order hold the system behaves as if additional dead-time had occurred in the system. Discrete PID controllers considering this effect are designed with pole cancellation technique.

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
This paper deals with a hybrid actuator composed by a piezo and a hydraulic part and with a cascade PID-PID control structure for camless engine motor applications. The idea is to use the advantages of both, the high precision of the piezo and the force of the hydraulic part.

On a generalization of pid regulators for delay systems *
IFAC Proceedings Volumes, 2001Abstract We derive PID-like regulators utilizing flatness-based predictive control (M. Fliess and R. Marquez, 2000, Continuous-time linear predictive control and flatness: a module-theoretic setting with examples, vol. 73, 606-623), generalized PI controllers (M. Fliess, R. Marquez, E. Delaleau, and H.

Multiresolution wavenet PID control for global regulation of robots
2013 9th Asian Control Conference (ASCC), 2013A novel global PID control scheme for nonlinear MIMO systems is proposed and synthesized for a robot manipulator. Identification process is used for online tuning of the discrete linear PID feedback gains. Inverse dynamics identification is based on radial basis neural network with daughter RASP1 wavelets activation functions in cascaded with an ...

PID-based regulation of background dynamics for foreground segmentation
2014 IEEE International Conference on Image Processing (ICIP), 2014In the area of foreground and background segmentation the dynamics of a scene often influence the model of the background. There exist different methods trying to overcome the difficulty in estimating and handling these dynamics. In this paper, we propose an adaption of proportional-integralderivative (PID) controllers to this regulation problem.

A class of nonlinear PID global regulators for robot manipulators
Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002In this paper we propose a class of nonlinear PID global regulators for manipulators which do not include their dynamics in the central law. The structure of this class of global regulators is based on a linear PD feedback, plus an integral action driven by a nonlinear function of the joint position error, and the addition of the gradient of a C/sup 1/

Nonlinear PID controller for the regulation of fixed bed bioreactors
Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2004The main issue of this paper is the synthesis of robust nonlinear PID control law for the regulation of the outlet substrate concentration in fixed bed bioreactor. The controller design is realized via a linearizing control law, which is coupled with a proportional-derivative reduced order observer to infer online the unknown kinetic terms related with

Pid-like regulators for a class of linear delay systems
2001 European Control Conference (ECC), 2001We derive a PID-like regulator utilizing flatness-based predictive control which can be seen as an extension of the Smith predictor. We also show how to avoid the use of derivatives of the measured output.

Stability analysis for the intermediate servo/regulation PID tuning
2009 IEEE Conference on Emerging Technologies & Factory Automation, 2009This paper introduces the stability analysis for the so-called intermediate-tuning PID controller. Thus, each of the three PID parameters is proposed to lie within the convex hull of two extreme values, being defined as the optimal tuning settings for servo and regulation modes respectively. The result ensures that all the PID controllers generated for
