Abstract: The PI+CI compensator is a simple reset compensator, its base system is a PI, which has been shown to be effective in a number of practical applications. One fundamental parameter to be tuned is the reset ratio; for lag dominant systems or systems with integrators it is known to give good results overcoming PI compensation. In this work, a systematic method for the tuning of a variabl...

Virtual master-slave concept is proposed to realize a human-machine interface for nonholonomic systems. In this concept, the virtual master system acts as an interface to control the slave system. The control architecture using this concept is based on a two degrees-of-freedom (DOF) design, where the neural network (NN) constructs a feedforward controller, whereas a compensator acts as a feedba...

In this paper, we test fuzzy logic-based compensation method for PID controller and conditioned Technique and compare their performance. As this compensation aims to diminish the effect of windup, it is referred to as anti-windup (AW). We consider two cases: set point tracking and disturbance rejection. For set point tracking and disturbance rejection, the fuzzy compensator shows better perform...

Abstract The formulation of a discrete-time anti-windup scheme for linear systems with constrained control signals is extended to the sampled-data case. Thus, the control of a continuous-time linear plant via a discrete linear nominal controller and a discrete anti-windup compensator is considered. Stability of the antiwindup compensator is equivalent to the known discrete problem while a hybri...

In this paper, the compensator based reduced order control design framework of 2] is modiied to yield low order systems with guaranteed stability margins. This result is achieved through use of a logarithmic barrier function. In addition, a reduced basis method is formulated in which the compensator equations are approximated on uneven grids; guaranteed stability margins are also included. The ...

The stability of reset control systems has been mainly studied for the feedback interconnection of reset compensators with linear time-invariant systems. This work gives a stability analysis of reset compensators in feedback interconnection with passive nonlinear systems. The results are based on the passivity approach to L2-stability for feedback systems with exogenous inputs, and the fact tha...

At large distances the electromagnetic field of a wire is the same as the field produced by a bunch. Such a longrange beam-beam wire compensator was proposed for the LHC, and single beam tests with wire compensators were successfully done in the SPS. RHIC offers the possibility to test the compensation scheme with colliding beams. We report on measurements of beam losses as a function of transv...

A backlash compensator is designed for nonlinear systems using the fuzzy logic. The classification property of fuzzy logic systems makes them a natural candidate for the rejection of errors induced by the backlash, which has regions in which it behaves differently. A tuning algorithm is given for the fuzzy logic parameters, so that the backlash compensation scheme becomes adaptive, guaranteeing...

The market for derivatives with payoffs contingent on the credit quality of a number of reference entities has grown considerably over recent years. The risk analysis and valuation of such multi-name structures often relies on simulating the performance of the underlying credits. In this paper we discuss the simulation of correlated unpredictable default arrival times. Our algorithm is based on...

This paper presents graphic-based simulation and optimal PI controller design of a static var compensator (SVC) using MATLAB’s SIMULINK. Utilization of MATLAB software simplifies problem solving complexity and also reduces working time. In this paper, an optimal PI controller design using genetic algorithms for the SVC was demonstrated. From which satisfactory controller design results, tests a...
