Summary:The invention provides a cannon servo-actuated system feedforward control method with a time lag taken into consideration. First of all, a given angle of a servo-actuated system at a current time point is acquired, then, an angle second-order differential signal estimation value, an angle first-order differential signal estimation value, an angle estimation value, the gain of a controlled object of the servo-actuated system and a first-order differential compensation coefficient at the current sampling time point are successively calculated, and finally, output of a feedforward controller is obtained. The feedforward control method provided by the invention realizes the servo-actuated system with a delay link, can overcome the influence brought by delay time to precision and improves the control precision of the servo-actuated system.
