⟡ Main research areas

1.   Radar servo control system

Radar servo control systems are widely used in various airborne/shipborne/ground radar systems. With the development of various new radar technologies, special requirements such as rapid speed and guaranteed accuracy, low speed and high accuracy have been put forward to the radar servo system. For example, the fast sector scan of the airborne anti-collision radar and the high accuracy tracking function of precision vectoring radar, and so on. Therefore, it is necessary to face the project engineering requirements and carry out research and engineering application verifications in the aspect of such as high-speed motion trajectory planning and stability compensation, precision control algorithms, new structure design, and the influence of servo mechanism structural factors on control performance. Presently, the products researched and developed have been applied to model products of airborne/shipborne/ground radar systems.

2.   Photoelectric stable tracking control system

The photoelectric stable tracking control system is widely applied in airborne photoelectric (visible light/infrared/laser) pods, on-board and shipborne photoelectric platforms. With the development of various photoelectric detection, tracking, fire control and other new technologies, special requirements such as higher isolation and faster tracking performance have been made on various photoelectric stable tracking platforms. Therefore, it is necessary to face the project engineering requirements, and carry out the research and engineering application verifications in the aspect of gyro-stabilized platform structure and intelligent control methods, strapdown stabilized platform compensation algorithm and disturbed coupling issues, filtering estimation issues of gyro and inertial navigation system signal, dead zone tracking issues, etc. Currently, the products researched and developed have been applied in pod products with diameters of 600mm, and 220mm, and so on.

3.   Missile borne seeker position marker servo system

The missile borne seeker position marker servo system is widely applied in various seekers (radar/visible light/infrared/laser) precision guidance systems. With the continuous update of the working system of seekers and the improvement of the all-weather and self-seeking capabilities, higher requirements have been proposed on the servo system, strong anti-vibration and shock characteristics, stable isolation, tracking precision, etc. of the missile borne seeker position marker servo systems. Therefore, it is necessary to face the project engineering requirements, and carry out research and engineering application verifications according to different application backgrounds in the aspect of seeker position marker new servo mechanism, disturbance isolation control algorithm, missile-body tracking control under the large acceleration condition, etc. Presently, the products researched and developed have been respectively applied in 1D, 2D radar seekers, and a small optical seeker product.

4.   Intelligent assembly system based on machine vision

The research contents of this area originate from the national pre-research projects during the 13th Five-Year Plan period. Its application background is the non-contact rapid measurement technology in the special position marker manufacturing and assembly. The measured objects are phased array antenna, servomechanism axial direction, optical dome and integrated frame. And it involves the research and application of key technologies such as the 3D precision measurement of flat large field of view, 3D entity reconstruction, and mechanism axial positioning. Meanwhile, the product testing and position recognition of automatic production lines and the automatic process control and development based on six-axis robots are also carried out.

5.   Dedicated special servo drive

In the practical application requirements of airborne radars, photoelectric pods, and seeker position marker servo control systems, special requirements such as light weight, small space, and special shaped layout are often put forward to the control and drive parts. Therefore, in the face of the engineering requirements, the research and development of the high density, miniaturization, special layout and integrated drive and control of DC brushed/brushless servo motor and AC servo motor drives are carried out. At present, the products researched and developed have been applied in airborne radars of a certain kind, small pods, and small seeker position marker products.

6.   Production process control system

This area mainly includes the research and development of the distributed process control systems assembled based on PLC, IPC and Profibus, the research and development of SCADA systems based on GPRS, radio stations, etc., and the research and development of dedicated monitoring instruments and equipment based on single-chip computers, DSP, and FPGA, and other contents. Combined with the scientific research requirements, carry out theoretical research on Profibus real-time performance, network control system characteristics, PLC upper and lower redundancy technologies, OPC technology, configuration software secondary development technology, special instrument signal processing, etc.
