N2 - Linear oscillating motor is the source of power in LEHA system and its heat dissipation performance plays an important role in achieving high power density. To enhance cooling capacity, flooded motor is generally adopted as a solution, which utilizes oil for cooling and lubrication. However, oil-film lubrication always causes severe decline of system damping ratio and deteriorates control stability. In this paper, dual-feedback control strategy is proposed to improve system damping ratio and enhance control resolution. Firstly, dynamics model of flooded motor is set up. Based on this model, the underdamping characteristic is analyzed with dual-feedback and feed-forward controller proposed. In this controller, velocity and acceleration signals forms the dual-feedback channels; feed-forward channel is also included via reference signal. Finally, simulations and comparisons are conducted to prove the effectiveness of this method.
