Robust synthesis of feedforward compensators
The design of a feedforward compensator for robust H1 or H2 performance under structured uncertainty is considered. For linear time-invariant uncertainty, a convex method based on linear matrix inequalities (LMI’s) across the frequency variable is given. For nonlinear or time-varying perturbations and H1 performance, the design problem is reduced exactly to a state-space LMI, and extensions to ...
متن کاملOn robust control synthesis and analysis in a Hilbert space!
The motivation for this paper stems from the need to develop a uniform framework for addressing problems in identi!cation and robust control. System identi!cation for in!nite-dimensional Hilbert spaces has been addressed earlier by the authors. System identi!cation set in an Hilbert space results in uncertain models where the description of non-parametric error is typically a ball belonging to ...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولGuidance and Control Algorithms for the Mars Entry, Descent and Landing Systems Analysis
The purpose of the Mars Entry, Descent and Landing Systems Analysis (EDL-SA) study was to identify feasible technologies that will enable human exploration of Mars, specifically to deliver large payloads to the Martian surface. This paper focuses on the methods used to guide and control two of the contending technologies, a midlift-to-drag (L/D) rigid aeroshell and a hypersonic inflatable aerod...
متن کاملRobust Control of Electrically Driven Robots in the Task Space
In this paper, a task-space controller for electrically driven robot manipulators is developed using a robust control algorithm. The controller is designed using voltage control strategy. Based on the nominal model of the robotic arm, the desired signals for motor currents are calculated and then the voltage control law is proposed based on the current errors and motor nominal electrical model....
