Application of Genetic Algorithm in Optimizing LQR Control for Ball and Beam [PDF]

open access: yesRobotica & Management, 2023
In this paper, we apply genetic algorithm (GA) to optimize LQR controller – a linear control algorithm which stability is guaranteed by mathematics. This searching algorithm proves its ability in finding better control parameters through generations. Our

Quantile Credibility Models with Common Effects

open access: yesRisks, 2020
Different from classical Bühlmann and Bühlmann Straub credibility models in which independence between different risks are assumed, this paper takes dependence between risks into consideration and extends the classical Bühlmann model by introducing a ...

On the rise and fall of a ball with linear or quadratic drag [PDF]

open access: yes, 1999
We review the problem of a vertically thrown ball, with a drag force which is either linear or quadratic in the speed. It is stressed from the outset that these two types of drag correspond to specific ranges of the Reynolds number ...

Graphoidal graphs and graphoidal digraphs: a generalization of line graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
A graphoidal cover of a graph G is a collection ψ of paths (not necessarily open) in G such that each path in ψ has at least two vertices, every vertex of G is an internal vertex of at most one path in ψ, and every edge of G is in exactly one path in Let
