Noninvertible Digital Transfer Functions Arising From Minimum Phase Analog Process Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current approaches to discrete model reference adaptive control (MRAC) [1–6] require the inverse of the discretized process model to achieve the desired model following. The objective of this ...
Parameter Identification Using the Galerkin Procedure in Nonlinear Boundary-Value Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper introduces a computationally rapid and effective approach for parameter identification in both linear and nonlinear boundary-value problems. The technique proposed evolves around application ...
A Series-Parallel Identifier With Auxiliary Signals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Auxiliary signals which are proportional to the tracking error between the process and identifier outputs are introduced into the s eries-p arallel (SP) identifier [1-2]. The coefficients of ...
Linearization and Sensitivity Models of the Newton-Euler Dynamic Robot Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Within the framework of the Newton-Euler formulation of robot dynamics, linearized and trajectory sensitivity models are constructed about a nominal trajectory. The approach illustrates the property ...
