The Digital Servo System With Digital Tracking Filter Developed

The paper is composed of two parts.In the first part, a style of digital Servo-System is developed, which will be applied to the electronic interference device. The closed-loop control is realized by applying AC driving scheme, Resolver-to-Digital converter system and intelligent PID control strategy. The controller design basing on PC/104 bus is introduced in the paper. Experiment results show that good performance can be achieved when intelligent PID is applied. Finally, the design of the Servo-System for the jet is introduced.In the second part, a style of digital tracking filter is introduced, which is used in the phase steady system of a style of long-range rocket. The filter is required to filter some noises and keep against lag of system phase. A kind of nonlinear differential filter for the phase compensating, and the other filter basing on the phase and amplitude compensating are introduced in the paper. The filter designed is simulated by MATLAB and debugged in SCM. Finally, some beneficial suggestions are put forward for the far research.
