Vacuum booster control system design and fault self-check strategies

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) ...

Vacuum Booster for Distillation Process

Design of Fault Tolerant Flight Control System

The purpose of the paper is to present an approach to detect, isolate and accommodate the sensor or actuator faults using bank of observer and unknown input observers (UIO). Full order observers, reduced order observers, unknown input observers and Kalman Filter are widely used in state estimations [1]. After the estimation of states, fault detection and isolation can be provided by conducting ...

The vacuum control system design in ultracentrifuge chamber

The ultracentrifuge rotor usually works at 30,000 r/min or more, so centrifuge chamber must maintain a high vacuum to reduce friction of rotor and air. The paper described the vacuum control system design based on MSP430 microcontroller. The system included the MCU, sensors, measurement and conditioning circuitry, vacuum control circuit, power circuit components and so on. Tests proved that the...

New Strategies for Fault Tolerant Control and Fault Diagnostic

A recent architecture based on the Youla parameterization is analyzed for the nominal and uncertain case. This special architecture is characterized by a separation principle for the controller. In this paper, several stability results that allow to extend the structure to the integrated control/filter approach are presented. Two algorithms based on the recursive design and nesting of the integ...
