Abstract:

To further support the practicability of the digital hydraulic actuator as a control component, IBM has successfully demonstrated operation of the Phase III laboratory model in a simulated digital flight control system. Performance using the laboratory model is compared with the performance when using a mathematical model. Recorded transients and the values obtained for a maximum stable step and gain change are presented. The effect of varying the actuator parameters and the validity of a linearized model is also established. Agreement of the results shows the mathematical model to accurately represent the actual hardware. Hence, this study verified the results of both Phase I and Phase II.
