Solution to the positive real control problem for linear time-invariant systems
TL;DR: In this paper, the problem of synthesizing an internally stabilizing linear time-invariant controller for a linear time invariant plant such that a given closed-loop transfer function is extended strictly positive real was studied.
Journal ArticleDOI
Direct strain feedback control of flexible robot arms: new theoretical and experimental results
TL;DR: The introduction of the concept of (strict) A-dependent operators is introduced, which allows us to prove rigorously the closed loop stability of direct strain feedback and the existence and uniqueness of nonstandard second order abstract differential equations in Hilbert spaces.

Optimization Criteria for Optimal Placement of Piezoelectric Sensors and Actuators on a Smart Structure: A Technical Review
TL;DR: In this paper, the authors present various optimization criteria used by researchers for optimal placement of piezoelectric sensors and actuators on a smart structure, including modal forces/moments applied by actuators, maximizing deflection of the host structure, minimizing control effort/maximizing energy dissipated, maximizing degree of controllability, and minimizing degree of observability.
Robust controller design for flexible structures using normalized coprime factor plant descriptions
TL;DR: In this paper, the problem of finding the largest neighborhood around a given design plant for which a single controller produces closed-loop stability can be formulated as an H(sub infinity) control problem.
