We propose a method to assess the impact on power system dynamic performance of operational uncertainty caused by variability in the system supply side. Operational uncertainty is not new to power systems, e.g., demand variability. However, with the increased penetration of renewable-based generation, operational uncertainty will extend to a significant portion of the supply side, which may have an...
This paper presents an analytical framework for detecting the presence of jumps and impulses in the solutions of switched differential algebraic equations (switched DAEs). The framework can be applied in the early design stage of fault-tolerant power electronics systems to identify design flaws that could jeopardize its reliability. The system is described by a switched differential algebraic equation,...
The paper deals with squirrel cage induction generator connected to the grid through a back-to-back converter, which is driven by vector control. The stator side converter controls the generator torque using an indirect vector control. The grid side converter controls the DC Bus voltage and the reactive power. The proposed control strategy is validated by simulation in Matlab/Simulinkr®.
In this paper, a nonlinear passivity-based control strategy based on stability in the sense of Lyapunov (Second method) and sliding mode control applied to Euler-Lagrange systems (robot arms) and extended to the PHANToM Premium 1.0 haptic device for purposes of local haptic guidance rehabilitation and medical diagnosis in people who have some motor impairment (on upper limb) is designed and implemented.
In this paper a PID control applied particularly in robot manipulators. To understand the development of the proposal presents a mathematical preliminary section we used, we explicitly describe relevant aspects of kinematics and dynamics of the haptic device Phantom Premium 1.0, technology and mathematical models, and the design and experimental results of PID control based on passivity, the type...
This article presents the experimental verification of kinematic and dynamic models of the PHANToM Premium 1.0 haptic device. Dynamic properties are evaluated, in order to apply nonlinear control techniques and evaluation of manipulability and energy in real-time. Position kinematics and differential kinematics are validated for the trajectory planning by using joint control techniques for local haptic...
