A novel electromagnetic recuperator used in the artillery: Structural and control algorithm design

Aiming at the problem that the traditional artillery recuperator is difficult to maintain and control, a novel electromagnetic recuperator based on the principle of tubular permanent magnet synchronous linear motor is proposed. First, the structural scheme of the electromagnetic recuperator is designed, and the maximum thrust required for the artillery counter-recoil motion process is determined by force analysis. Secondly, according to the requirements of the artillery type and design, the analytical model of the electromagnetic recuperator is established by the subdomain method, and the main structural parameters can be obtained quickly. Then, the correctness of the analytical model is verified by the finite element method. Considering the complex uncertainties in the artillery counter-recoil control process, an adaptive robust control is proposed. The uncertainty of the system is estimated online using a leaky adaptive rate α, and the controller is compensated. Finally, the simulation results show that the designed electromagnetic recuperator meets the thrust requirements of the artillery counter-recoil process; adaptive robust control can effectively solve the uncertainty problem in the system and provides smaller stabilization time and steady-state tracking error compared to PID control.
