Abstract:

In order to improve the efficiency of the development of optical-mechanical scanning controller for space remote sensor, a development and test system is designed for the most frequently used actuator and angle-measuring device. The system is used to test the parameter of dynamics, kinematics and angle-measuring, develop a rapid control prototype, forming a closed loop of development and test to improve the controller’s accuracy. The structure and parameter of the develop and test system, the structure of rapid prototype with the real-time hardware platform, and the information integration platform is introduced in detail. Using brushless DC motor, the simulator of rotary transformer, and the rapid prototype to test the system, the results prove the system can test and develop optical-mechanical scanning controller rapidly and accurately.
