Alocação de zeros aplicada a sistemas de controle via LMI
A systematic procedure of zero placement to design control systems is proposed. A state feedback controller with vector gain K is used to perform the pole placement. An estimator with vector gain L is also designed for ...
Narrowband feedback for narrowband control of resonant and non-resonant vibration
This paper presents a simple feedback methodology that uses second order filters to control narrowband resonant and non-resonant vibration of a structural system. In particular, a single degree-of-freedom system is studied ...
Síntese de sistemas estritamente reais positivos através do critério de routh-hurwitz
Given a linear time-invariant plant Gol(s) with one input and q outputs, where q > 1, a method based on the Routh-Hurwitz Stability Criterion is proposed to obtain a constant tandem matrix F ∈ ℝq, such that FGOl(s) is a ...
The dynamic behavior of a parametrically excited time-periodic MEMS taking into account parametric errors
Micro-electromechanical systems (MEMS) are micro scale devices that are able to convert electrical energy into mechanical energy or vice versa. In this paper, the mathematical model of an electronic circuit of a resonant ...
Output control of continuous-time uncertain switched linear systems via switched static output feedback
This paper is devoted to the robust (Formula presented.) and guaranteed cost control problems for continuous-time switched linear systems with polytopic uncertainties, considering an output-dependent switching law and a ...
OPTIMAL H(INFINITY)-STATE FEEDBACK-CONTROL FOR CONTINUOUS-TIME LINEAR-SYSTEMS
(Plenum Publ CorpNew York, 1994)
A Dynamic-State Feedback Approach Employing a New State-Space Description for the Fast Wavelet Transform with Multiple Decomposition Levels
This research paper proposes a wavelet-based dynamic-state feedback control strategy in the discrete time domain. In this proposal, the state feedback employs a state-space description for the fast wavelet transform, which ...
Microcantilever chaotic motion suppression in tapping mode atomic force microscope
The tapping mode is one of the mostly employed techniques in atomic force microscopy due to its accurate imaging quality for a wide variety of surfaces. However, chaotic microcantilever motion impairs the obtention of ...
Nonlinear control system applied to atomic force microscope including parametric errors
The performance of the optimal linear feedback control and of the state-dependent Riccati equation control techniques applied to control and to suppress the chaotic motion in the atomic force microscope are analyzed. In ...
