Speed Adaptive Inversion Control of PMSM for Chain Gun

链式炮外能源电机转速稳定性对其射速影响很大。提出交流永磁同步电机(permanent magnet synchronousmotor,PMSM)的变参自适应反演速度稳定控制器设计方案,采用实时在线的自适应参数估计和反演控制相结合的方法,通过设计恰当的输入控制律,并对定子电阻、转动惯量、摩擦系数、负载转矩等参数按照设计的自适应估计律在线估计。试验结果表明:该控制策略能有效地抑制多参数摄动和负载扰动对转速的影响,可以作为一种较好的鲁棒方法在链炮伺服电机控制中采用。

The speed stability of external power motor affects fire ratio of chain gun heavily. The adaptive inversion controller is designed to satisfy the high performance of rotate speed of permanent magnet synchronous motor （PMSM） for chain gun system. Real-time adaptive parameter estimation is combined to restrain the effect of parametric uncertainty and load torque disturbance. Through design input control law to stator resistance, moment of inertia, friction coefficient, load torque, etc progress online estimation in the light of adaptive estimation law. The simulation results show the control strategy is perfect efficient to reduce the effect of variable parameter and load. This robust approach should be adopted in controlling of chain gun.
