Power electronics based power distribution systems (PEDSs) can offer excellent load regulation, transient performance, and, with proper architecture, a high degree of fault tolerance. They are excellent candidates in power distribution systems that need to be fullyor semi-autonomous. Typical applications include ships [1], submarines [1], aircraft [2, 3],(More)
Real-time approximators for continuous-time dynamical systems with many inputs are presented. These approximators employ a novel self-organizing radial basis function (RBF) network, which varies its structure dynamically to keep the prescribed approximation accuracy. The RBFs can be added or removed online in order to achieve the appropriate network(More)
Stability is an important design consideration in power electronics based power systems such as those on electric ships. Generalized immittance based stability analysis is one approach to addressing this design consideration. In this paper, refinements to the generalized immittance based stability analysis approach are proposed. This include the(More)
High performance high bandwidth control of power electronic converters, inverters, and motor drives has become feasible over the past decade. These devices behave as constant power loads over large bandwidths when they are tightly regulated. However, constant power loads have a severe side affect known as negative impedance instability. In order to mitigate(More)
Direct adaptive robust state feedback and output feedback controllers are proposed for the output tracking control of a class of uncertain systems with disturbance. The proposed controllers employ self-organizing raised-cosine radial basis function networks, which are capable of determining their structures dynamically, to approximate unknown system(More)
Microgrid power systems are becoming increasingly common in a host of applications. In this work, the mitigation of the adverse affects of pulsed-power loads on these systems is considered. In microgrid power systems, pulsed loads are particularly problematic since the total system inertia is finite. Examples include ships and aircraft with high-power(More)
This paper sets forth a new approach to robust evolutionary computing. In particular, the proposed approach allows users to specify the probability of success in meeting design specifications in the presence of uncertainties. Three benchmark problems have been considered to demonstrate the proposed approach. In addition, a robust electromagnet design(More)
This paper addresses equivalent circuit and magnetic saturation issues associated with synchronous machine modeling. In the proposed synchronous machine model, the rotor equivalent circuits are replaced by arbitrary linear networks. This allows for elimination of the equivalent circuit parameter identification procedure since the measured frequency response(More)
