Journal ArticleDOI
A fuzzy inference engine in nonlinear analog mode and its application to a fuzzy logic control
TL;DR: In this tutorial, the utility of a fuzzy system is demonstrated by providing a broad overview, emphasizing analog mode hardware, along with a discussion of the author's original work.
Journal ArticleDOI
Variable-structure PID control to prevent integrator windup
A. Scottedward Hodel,C.E. Hall +1 more
TL;DR: A new variable-structure (switching) method for the prevention of proportional-integral-derivative controller integrator windup in both continuous and discrete-time implementations is proposed.
Journal ArticleDOI
A novel time-domain auto-regressive model for structural damage diagnosis
TL;DR: In this article, a linear dynamic system theory-based approach is proposed for the diagnosis of structural damage, where only response (acceleration) signals are involved, with response at one location chosen as the "input" of the model.
Journal ArticleDOI
A multimaterial electrohydrodynamic jet (E-jet) printing system
Erick Sutanto,Kazuyo Shigeta,Yerim Kim,Phil Graf,David J. Hoelzle,Kira Barton,Andrew G. Alleyne,Placid M. Ferreira,John A. Rogers +8 more
TL;DR: In this paper, the design, integration and operation of a unique E-jet printing platform is discussed, where the uniqueness lies in the ability to utilize multiple materials in the same overall printhead, enabling increased degrees of heterogeneous integration of different functionalities on a single substrate.
Journal ArticleDOI
Improved Online Identification of a DC–DC Converter and Its Control Loop Gain Using Cross-Correlation Methods
Adam Barkley,Enrico Santi +1 more
TL;DR: In this article, several improvements to the cross-correlation method of system identification are proposed that aim to further improve the accuracy of the frequency response identification, particularly at high frequencies near the desired closed-loop bandwidth frequency.

Dynamic Phasor Estimates Under the Bellman's Principle of Optimality: The Taylor-LQG-Fourier Filters
TL;DR: The optimal linear quadratic (LQ) control is applied to design feedback filters referred to as TaylorK-LQG-Fourier filters and provides estimates of the instantaneous frequency, and its rate of change, preserving its synchrony with the signal for control applications.
Proceedings ArticleDOI
Discrete time robust stability design of PID controllers autonomous sailing vessel application
Tooran Emami,Richard J. Hartnett +1 more
TL;DR: This paper presents a successful graphical technique for finding all discrete-time proportional integral derivative (PID) controllers that satisfy a robust stability constraint for heading control of a 2 meter autonomous sailing vessel.
Journal ArticleDOI
Comments on “Digital Current Control in a Rotating Reference Frame—Part I: System Modeling and the Discrete Time-Domain Current Controller With Improved Decoupling Capabilities”
TL;DR: In the note, it is verified that having a precise model of the plant allows us to fulfill the control objective of obtaining the complete decoupling between axes.
Proceedings ArticleDOI
Direct approach to image edge detection using differentiators
TL;DR: This work addresses employing a direct approach to edge detection without using masks by using IIR differentiators, knowing that IIR digital filters outperform the same order FIR filters.
Journal ArticleDOI
Δ-Entropy: Definition, properties and applications in system identification with quantized data
TL;DR: A new entropy definition for the discrete random variables, i.e. the @D-entropy, based on Riemann sums for finite size partitions is given, which is sensitive to the dynamic range of the data, and can be used as a superior optimality criterion in system identification problems.
