N2 - The three-dimensional momentum wheel platform is a typical nonlinear strong coupling system. For the characteristics of the nonlinear strong coupling of the platform, this paper linearizes it based on the offline genetic algorithm, and designs the LQR-PI controller based on the linear model to achieve the attitude control of the platform. Through the change of the system state matrix and the linearization and fitting of the input and output data set, the linear model of the system is obtained, and compared with the traditional linearization model based on Taylor expansion, the simulation results show the LQR-PI controller designed by the linearization method used in this paper for the three-dimensional momentum wheel platform has stronger control performance and robustness, which further illustrates the effectiveness and advantages of this method.
