Sliding mode controller for a vehicle active suspension system is designed in this study. The widely used quarter car model is preferred and it is aimed to improve the ride comfort of the passengers. The effect of the actuator time delay, which may arise due to the information processing, sensors or actuator dynamics, is also taken into account during the design of the controller. A sliding mod...
A new method for robust fixed-order H∞ controller design for uncertain time-delay systems is presented. It is shown that the H∞ robust performance condition can be represented by a set of convex constraints with respect to the parameters of a linearly parameterized primary controller in the Smith predictor structure. Therefore, the parameters of the primary controller can be obtained by convex ...
By relating a novel predictive controller to LQ designs stability theorems are deduced, and extensions to Generalized Predictive Control give model following, state-dead-beat and pole-placement control objectives. Abstract-The original GMV self-tuner was later extended to provide a general framework which included feedforward compensation and user-chosen polynomials with detuned model reference...
The stabilization by feedback control of systems with input delays may be considered in various frameworks; a very popular is the abstract one, based on the inclusion of such systems in the Pritchard-Salamon class. In this paper we consider the elementary approach based on variants of the Smith predictor, make a system theoretic analysis of the compensator and suggest a computer control impleme...
This paper presents a novel, practically implementable robust Power Control (PC) technique that is generally applicable to a variety of IEEE 802.15.4 infrastructure and peer-to-peer wireless sensor networks (WSNs) where there is a round-trip time-delay uncertainty. In thismethodology, robust stability and performance constraints are cast as a set of exclusion regions on the Nichols chart. The d...
High control bandwidth is usually restricted in a photoelectric tracking system (PTS) based on Charge-Couple Device(CCD) with time delay, which hinders good performance. Generally, model-based delay-compensation controller called Smith predictor (SP) can help increase the gain to promote by separating delay from loop. However, performance promotion insufficient because still stays forward chann...
