RISSingle-Axis Gyroscopic Motion With Uncertain Angular Velocity About Spin Axis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A differential game approach is presented for studying the response of a gyro by treating the controlled angular velocity about the input axis as the evader, and the bounded but uncertain ...
Stabilizing Feedback Controls for Nonlinear Hamiltonian Systems and Nonconservative Bilinear Systems in Elasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using the invariance principle of LaSalle [1], sufficient conditions for the existence of linear and nonlinear control laws for local and global asymptotic stability of nonlinear Hamiltonian ...
Flow About a Stationary Sphere in a Slowly Rotating, Viscous Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analytical solutions are presented for the flow about a nonrotating sphere immersed in a slowly rotating fluid by the singular perturbation technique valid for small Reynolds numbers. Streamlines ...
Sliding Mode Control and Elastic Mode Stabilization of a Robotic Arm With Flexible Links
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper treats the question of control of an elastic robotic arm of two links based on variable structure system (VSS) theory and pole assignment technique for stabilization. A discontinuous ...
Robust Trajectory Following Control of Robotic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using an inversion approach we derive a control law for trajectory following of robotic systems. A servocompensator is used around the inner decoupled loop for robustness to uncertainty in the ...
Control of Elastic Robotic Systems by Nonlinear Inversion and Modal Damping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Energy efficient, lightweight robot arms for space applications have considerable structural flexibility. For large and fast motions, both the nonlinear coupled dynamics and the elastic behavior ...
Nonlinear Control of Mismatched Uncertain Linear Systems and Application to Control of Aircraft
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an approach to control of nonzero set points of uncertain linear systems based on the theory of ultimate boundedness. We derive a nonlinear control which guarantees that ...
Linear Feedback Control of Boundary Layer Using Electromagnetic Microtiles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a system-theory approach to control of a two-dimensional turbulent flow of saltwater on a flat plate using Lorentz forces produced by microtiles of small magnets and electrodes. ...
Decoupling in a Class of Nonlinear Systems by State Variable Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For a class of nonlinear systems we derive a necessary and sufficient condition for the existence of a state variable feedback control law which accomplishes decoupling, as well as some ...
Influence of Bidding Mechanism and Spot Market Characteristics on Market Power of a Large Genco Using Hybrid DE/BBO
Publisher: American Society of Civil Engineers
Abstract: Generation company (Genco) bidding in an electricity market (EM) aims to maximize its profit under uncertain market characteristics and a regulated bidding mechanism. This paper addresses the strategic bidding for a large ...
