Abstract:
The problems and challenges of designing the closed-loop electronic control of a Direct Drive Valve (DDV) actuator system are discussed. Advantages and disadvantages of the DDV concept compared to the Electro-Hydraulic Valve (EHV) are outlined. Loop closure servoamplifier design, failure monitoring, current equalization, and testability of the DDV are also discussed. The Taiwanese Indigenous Defensive Fighter (IDF) serves as the testbed for the design, integration, and testing of one such DDV system.
