Differentially Positive Systems [PDF]
IEEE Transactions on Automatic Control, 2015 The paper introduces and studies differentially positive systems, that is, systems whose linearization along an arbitrary trajectory is positive. A generalization of Perron Frobenius theory is developed in this differential framework to show that the property induces a (conal) order that strongly constrains the asymptotic behavior of solutions.

Positive observers for semilinear positive systems
IMA Journal of Mathematical Control and Information, 2022 Abstract The problem of designing a positive Luenberger observer for a class of infinite-dimensional semilinear positive systems is addressed. The proposed observer is positive. That is, it ensures that the state estimates are non-negative at any time. The positive observer is designed based on positive bounded perturbation results.

Delay-Time Adjustable Input Shaping Method for Positioning Systems Subject to Repetitive Motion [PDF]
한국정밀공학회지, 2020 Most positioning systems experience residual vibration during operation. Such residual vibration can be eliminated or reduced to an acceptable level by using the input shaping method.
