Systems With Distributed Parameters

This paper deals with the high gain feedback stabilization of single input–single output (SISO) minimum-phase systems with distributed parameters. Sufficient conditions for an infinite-dimensional SISO system to be stabilized by a high gain output feedback are obtained. The results of this paper are useful for designing and tuning high gain output feedbacks in numerous industrial control applications.

Main Operating

A high gain three port converter with a unidirectional port for photovoltaic (PV) side and two bidirectional ports one each for the battery and the DC bus for PV integration to DC microgrid is presented. High gain is achieved by a coupled inductor with switched capacitor, whereas single stage conversion is used between the ports to achieve high efficiency. The proposed converter is modelled in PLECS/MATLAB and the simulated results for various operational modes are validated using a 500 W prototype. For main operating mode, i.e., single input single output (SISO), the efficiency is calculated to be as high as 96 %. Similarly, owing to the reduced number of components, the losses are reduced considerably for different operation modes.

Siso Systems

This paper describes how the minimal controller synthesis (MCS) algorithm is combined with the minimal observer synthesis (MOS) algorithm to produce an output feedback control structure in which no prior knowledge of plant state parameters is required. While the principal results relate to single-input single-output (SISO) systems, extensions to a particular class of multi-variable systems is discussed. Implementation and simulation examples are included to illustrate the effectiveness of the proposed scheme.
