Abstract
A digital computer-based state variable controller has been designed and applied to the 70-m antenna axis servos. The general equations and structure of the algorithm and provisions for alternate position error feedback modes to accommodate intertarget slew, encoder referenced tracking, and precision tracking modes are described. Development of the discrete time domain control model and computation of estimator and control gain parameters based on closed loop pole placement criteria are discussed. The new algorithm has been successfully impicmented and tested in the 70-m antenna at Deep Space Station (DSS) 63 in Spain.
