Optimal Control of Active Recoil Mechanisms
A servo-valve feedback system with variable control law is proposed for modification of a conventional hydropneumatic recoil mechanism to minimize peak recoil force for any round fired. Phase-plane-delta method of digital simulation is used to simulate the recoil mechanism model. An objective functi...

| description | A servo-valve feedback system with variable control law is proposed for modification of a conventional hydropneumatic recoil mechanism to minimize peak recoil force for any round fired. Phase-plane-delta method of digital simulation is used to simulate the recoil mechanism model. An objective function with direct physical interpretations is developed and non-linear optimization techniques are used to design feedback gains for each firing round. The method is applied to M37 recoil mechanism and significant improvement in recoil force trajectories is obtained. |
