英文摘要

      The networked multi-turntable system has many important applications in the field of aerospace. In this paper, the scenario was considered with a group of servo turntables pointing to a line target, and the control problem was formulated of realizing a uniform collinear distribution of the projection points. Firstly, a position control protocol for the formation of projection points was constructed on the projection plane. By using the nonlinear invertible coordinate transformation relationship between aiming point position and turntable attitude angle, the multi-turntable attitude angle cooperative control protocol is obtained. With the knowledge of matrix eigenvalues, the convergence conditions of the algorithm were analyzed, and the simulation environment of several two-degree-of-freedom rotating platform identification models in the loop was constructed. The effectiveness of the protocol was verified and the influence of design parameters on the convergence rate and stability was analyzed.
