Rotorcraft vibration control: adaptive vs LPV methods

, 2015
This paper proposes a parameter-varying approach for the vibration control problem in rotorcraft applications. The proposed algorithm can be considered as a variant of Harmonic Control (HC), and can be placed beside existing adaptive versions used in the

Order Linear Parameter-Varying Systems

, 2018
We present in this paper gain-scheduling composite nonlinear feedback (CNF) control for a set of second-order linear parameter-varying (LPV) systems that capture commonly used plant models in automatic control.

Identification of Continuous-Time Linear Parameter Varying Systems With Noisy Scheduling Variable Using Local Regression

IEEE Access
Some nonlinear systems can be represented through linear parameter varying models. In this work, we address the estimation of continuous-time linear parameter varying models in output error form, using a refined instrumental variable method.

Output Feedback Fault Tolerant Control for Linear Parameter Varying Plants Considering Imperfect Fault Information

IEEE Access
This study focuses on the design of an integral sliding mode-based fault-tolerant control allocation (ISM-FTCA) scheme for the class of uncertain linear parameter varying (LPV) systems.

LPV control of a gyroscope with inverted pendulum attachment

, 2018
\u3cp\u3eA linear parameter varying (LPV) optimal L\u3csub\u3e2\u3c/sub\u3e gain controller is designed with mixed-sensitivity shaping to stabilize an inverted pendulum attached to a control moment gyroscope (CMG). Swing-up of the pendulum is achieved by

On the Identification of Time Varying Structures [PDF]

The identifiability of reduced form econometric models with variable coefficients is investigated using the control theoretic concepts of uniform complete observability and uniform complete controllability.

Monetary Policy Transmission under Zero Interest Rates: An Extended Time-Varying Parameter Vector Autoregression Approach [PDF]

This paper attempts to explore monetary policy transmission under zero interest rates by explicitly incorporating the zero lower bound (ZLB) of nominal interest rates into the time-varying parameter structural vector autoregression model with stochastic ...

The Kalman Foundations of Adaptive Least Squares: Applications to Unemployment and Inflation [PDF]

Adaptive Least Squares (ALS), i.e. recursive regression with asymptotically constant gain, as proposed by Ljung (1992), Sargent (1993, 1999), and Evans and Honkapohja (2001), is an increasingly widely-used method of estimating time-varying relationships ...
