Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] In the photoelectric tracking system, multiple hysteresis correctors are cascaded and overlapped under certain rules to achieve relatively smooth control gain enhancement and phase loss in the working frequency band. While effectively improving the tracking accuracy of the photoelectric tracking system, Satisfy a certain system stability margin requirement.

[0021] The present invention is directed at the photoelectric tracking system, which can be considered as a linear constant system with single input and single output in its working frequency band, and can be represented by transfer function G(s), r(t) is the tracked input signal, y(t ) is the actual tracking position of the photoelectric tracking system. Since the system always has delay effects caused by signal sampling, transmission, etc. during operation, the co...

Abstract

The invention discloses a multistage multi-order lag correction network control method for a photoelectric tracking system, and the method employs a multistage multi-order lag correction network whichis arranged according to a specific rule, and achieves high-precision tracking in the working frequency band of the photoelectric tracking system and automatic setting of control parameters under theconditions that an existing control system frame does not need to be changed and the relative stability of the system is not affected. Compared with an existing photoelectric tracking control system,the photoelectric tracking control system has the advantages that the contradiction problem between the tracking precision and the stability in the current photoelectric tracking system is weakened while the tracking precision is improved, and the problems of fuzzy design basis and parameter setting of designers in design are solved.

Description

technical field [0001] The present invention relates to the control field of photoelectric tracking system, in particular to a multi-level and multi-order lag correction network control method for photoelectric tracking system, which is suitable for high requirements on tracking accuracy and stability margin, and does not require designers to have rich control system design experience A high-precision photoelectric tracking system that can be quickly realized. Background technique [0002] In the fields of photoelectric measurement, laser communication, and astronomical observation, the photoelectric system plays an important role as an actuator for quickly and accurately discovering and tracking targets. In recent years, with the increase of the detection distance, the rapidity and maneuverability of tracking targets, higher requirements have been put forward for the tracking accuracy of the photoelectric tracking system, which poses challenges to the corresponding photoele...
