Control System Design and Fault-Ride-through Performance Analysis of Grid-Connected Microturbine Generation System

In recent years, microturbines as one the distributed generation sources have widly used. This paper investigates the control structure of the microturbine and analyzes its performance in grid-connected mode. In this way, first, the mechanical model of the microturbine is presented. Then, the electrical structure of the microturbine, consisting  of permanent magnet synchronous generator (PMSG) ...

Optimization in Control System Design

Abstmct This paper reviews i) the background for the modern Hw control theory, and then ii) how it led to the modern optimization theory such as those using LMIs (linear matrix inequalities) and BMIs (bilinear matrix inequalities). Starting from the simplest sensitivity minimization problem, we give solutions via the Nevalinna-Pick interpolation and the Nehari theorem. The latter lea,ds to a Ri...

Actor-Oriented Control System Design

Complex control systems are heterogeneous, in the sense of discrete computer-based controllers interacting with continuous physical plants, regular data sampling interleaving with usually irregular communication and user interaction, and multilayer and multimode control laws. This heterogeneity imposes great challenges for control system design technologies in terms of end-to-end control perfor...

Electrohydraulic System Design and Control

This paper deals with the position control of a hydraulic actuator regulated by a proportional directional control valve. The control algorithms based on the proportional-derivative controller have been applied to a specially designed two-channel electro-hydraulic servo system, which has the capacity to experimentally simulate common circumstances of a typical fluid power circuit. The first sys...
