Abstract:
Aimed at the electromagnetic formation flying (EMFF) ground testbed, an optimal linear quadric regulator (LQR) and sliding mode controller (SMC) are both proposed in this paper. Firstly, the highly nonlinear characteristics of the electromagnetic force and torque are analyzed. Then, the nonlinear dynamics equations are linearized, the controllability of the linearized system is analyzed, the optimal linear quadric regulator is then presented. Moreover, a sliding mode controller is also presented. Finally, the numerical simulation is carried out to compare LQR and SMC, and demonstrate the robustness of SMC. The results show that the SMC is more effective than LQR, which pave the way for electromagnetic formation flying ground simulation.
