Impedance-based stability analysis normally splits an interconnected system into source and load subsystems and the stability of the closed loop system can be analyzed by the combined input-output gains of source and load. This is an intuitive approach in the case of Single-Input Single-Output (SISO) systems. However, in the case of grid-tied voltage source converter (VSC) systems, dq impedance...

An algorithm is presented which computes a state feedback for a standard linear system which not only stabilizes, but also dampens the closed–loop system dynamics. In other words, a feedback gain matrix is computed such that the eigenvalues of the closed–loop state matrix are within the region of the left half– plane where the magnitude of the real part of each eigenvalue is greater than that o...

In this paper, a novel resilient multi-echelon closed-loop location-allocation-inventory problem (RMCLIP) is addressed that optimizes strategic and tactical decisions simultaneously. In order to represent the purchasing cost of raw material from the supplier, a pricing model under quantity discounts is employed in the closed-loop supply chain (CLSC). Considering the capability of returning the ...

Joint flexibility is a very important factor to consider in the controller design for robot manipulators if high performance is expected. Most of the research works on control of flexible-joint robots in literature have ignored the actuator dynamics to avoid complexity in controller design. The problem of designing nonlinear controller for a class of single-link flexible-joint robot manipulator...

Remanufacturing is an industrial process that makes used products reusable. Remanufacturing is a way to establish a closed-loop supply chain. One of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. In addition, in this paper the researchers have tried to present a mathema...

We develop a method to simplify the partial differential equations (PDEs) associated to the potential energy for interconnection and damping assignment passivity based control (IDA-PBC) of a class of underactuated mechanical systems (UMSs). Solving the PDEs, also called the matching equations, is the main difficulty in the construction and application of the IDA-PBC. We propose a simplification...

In a multiple-input multiple-output (MIMO) channel, created by employing multiple antennas at the transmitter and receiver, the system capacity and diversity dramatically increase. In a view of diversity, the space time block code (STBC) was proposed to enhance diversity gain. On the other hand, the bell labs layered space time architecture (BLAST) can achieve full data rate. To achieve both ad...

This paper presents a fault-tolerant attitude control scheme, incorporating reconfiguration allocation for supersonic tailless aircraft subject to nonlinear characteristics, actuator constraint, uncertainty, and faults. The main idea is propose an incremental closed-loop coupled with basic backstepping controller, achieve control. Based on the virtual input generated by firstly, method adopted ...

Recent results by the authors have shown how to construct a class of structured controllers for large scale spatially interconnected systems via linear matrix inequalities. Of paramount importance in the control of interconnected systems is that the controlled system be stable when arbitrarily small communication delays are present between subsystems. In this paper, it is shown how to realize t...
