Pointing Precision

With the rapid development of computer technology, it is widely used in the control field, including advanced alarm plane,cruise missile,radar,O-E theodolite,etc. The increasing complex and real-time arithmetic was applied in the ATP(Acquire Tracking Pointing) system of the control system for boosting the track、captring and pointing precision of O-E(photo-electric) theodolite, so it demanded the servo controller must complete more and more operations in shorter time. While the actual O-E theodolite accomplished the capture and tracking etc. based on PC104 system, so designed the servo control system based on embedded chip as CPU from the practicality, not only decreases the cubage of the system, but also increases the reliability and precision.

Simulation Results

Using the Fuzzy PID’s control method into the servo control system and the PID parameters can be adjusted real-time according to the simulation results, which corrects the system. Increasing the adaptabilities for the parameters’ real-time changings to improve the controlled object’s steady and dynamic performance, the system’s control precision and the capability of anti-jamming. With the help of MATLAB's FUZZY toolbox, the system’s control performance is tested in the aspects of system modeling and simulation.

Discharge Gap

In electro discharge machining (EDM) for 3D micro structures, the electrode wear is serious and it needs to be compensated in process. To obtain a better balance of the machining accuracy and efficiency, a servo scanning EDM method is proposed for 3D micro structures, in which the electrode wear is compensated on real-time by controlling the discharge gap constant. It is supposed reasonably that the machining depth of each layer in servo scanning EDM is consistent if discharge gap is kept preferably. The servo scanning EDM strategies include the model design by Pro/Engineer (Pro/E), the plan and simulation of scanning path, and the machining process. The 3D micro structures are machined by scanning layer-by-layer under servo control of the electrode with monitoring discharge gap signal. The CAM, gap servo control, and real-time electrode wear compensating are integrated into the machining system. The evaluation experiments of servo scanning EDM and the typical machining experiments of 3D micro structures have been carried out. The machining results show that the electro discharge in the servo scanning EDM is more stable. Servo scanning micro EDM is propitious to improve machining accuracy and efficiency in 3D micro structures.

Servo Control System

For the shipborne satellite antenna system，owing to the continuous change of the carrier’s position and pose as the time passing, we must conduct real-time measurement on the pose of satellite antenna, so that the satellite can be aimed through servo control system. In this paper, the hardware and software about the shipborne satellite antenna system are introduced. Three-dimensional closed-loop servo control system which is made of three kinds of pose sensors is implemented to isolate the links between the antenna pose and the carrier’s position and pose. FSK serial communication is adopted to realize a reliable control commands and data transmission between the control unit above the deck and the control unit under the deck. Conical spiral scan based on the best AGC signal realizes automatic tracking satellite and locking it. The result of the examination shows that the pointing of antenna is of steadiness, precision(the point precision is less than 0.3 degrees), real time and speediness(the capture time is less than 25 seconds ).
