Abstract


Triaxial inertial test turntable is one of the key equipment components . With the aerospace, aviation industry, the precision inertial element is ever increasing, but also the performance of the test turntable increasingly demanding . In this paper, the actual project as the background, focused on the design of its hardware system design and development as well as its controller . In this thesis, mainly for the following aspects of work : one describes the research background and significance of the comprehensive review of the development status of foreign -axis turntable , presented the main research content. Two general indicators by analyzing the turntable , to determine the FPGA DSP hardware platform for the system to DC torque motor as the control object to inductosyn angle sensor to measure the overall program design . Three characteristic parameters for the turntable conducted DC torque motor , as well as the modeling of the entire system , and uses all-digital PID algorithm for system simulation , the simulation results are analyzed . Four for the turntable load torque during operation of uncertainty , fuzzy control methods proposed for turntable control , elaborated fuzzy PID controller design method to determine the structure of the fuzzy controller , fuzzy control rules , parameters fuzzification , fuzzy inference and defuzzification methods, etc. , and the conventional PID control and fuzzy PID control law rule comparison shows that fuzzy PID controller is a superior performance of the controller. Finally, elaborated in practice some of the ideas PID parameter adjustment . Five turntable system for the existence of some nonlinear problems put forward some solutions.
