SPACE SHUTTLE POGO ACTIVE CONTROLLER DESIGN USING FREQUENCY DOMAIN OPTIMIZATION

摘要

A frequency domain parameter optimization technique was used to design active pogo suppression controls for the space shuttle. The technique uses a conjugate gradient search procedure and is well suited for designing low-order controllers for higher order systems. The shuttle model was a two-pump and six-structural-mode linear model representing a worst-case condition. A prom¬ising feedback controller structure was found to be a lead-lag design.
