Estimation of the Order and Parameters of a Fractional Order Model From a Noisy Step Response Data1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with integral based methods to estimate the order and parameters of simple fractional order models from the extracted noisy step response data of a process. This data can be obtained from both openloop and ...
Simultaneous Compensation of the Gain, Phase, and Phase Slope
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the problem of simultaneous compensation of the gain, phase, and phaseslope at an arbitrary frequency by using a fractionalorder lead/lag compensator. The necessary and sufficient conditions for ...
Robust Stability Analysis of Distributed-Order Linear Time-Invariant Systems With Uncertain Order Weight Functions and Uncertain Dynamic Matrices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bounded-input bounded-output (BIBO) stability of distributed-order linear time-invariant (LTI) systems with uncertain order weight functions and uncertain dynamic matrices is investigated in this paper. The order weight ...
Optimal Tuning for Fractional Order Controllers: An Integer Order Approximating Filter Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper offers a systematic framework for the design of suboptimal integerorder controllers based on fractionalorder structures. The proposed approach is built upon the integerorder approximations that are traditionally ...
On Robust Control of Fractional Order Plants: Invariant Phase Margin
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, a robust controller has been proposed to be used in control of plants with large uncertainty in location of one of their poles. By using this controller, not only the phase margin and gain crossover frequency are ...
Adaptive Consensus Tracking for Fractional Order Linear Time Invariant Swarm Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an adaptive controller to achieve consensus tracking for the fractionalorder linear time invariant swarm systems in which the matrices describing the agent dynamics and the interactive dynamics between ...
