Embodiment Construction

[0015] Such as figure 1 , figure 2 As shown, a control method based on linear servo motor is realized in this way. Firstly, the autonomous decentralized control method is introduced into the control of permanent magnet linear synchronous motor, and the linear motor mathematical model under autonomous decentralized control is established. Through the autonomous decentralized control The current loop design of the catapult makes the system have a faster response characteristic, and the control method of the linear motor of the electromagnetic catapult includes the following steps:

[0016] 1. According to the law of electromagnetic induction and Kirchhoff's voltage law, before the stator three-phase winding is split, the stator voltage equation of the linear motor in the stationary coordinate system can be written as

Abstract

A control method based on a linear servo motor comprises the following steps: 1, according to the requirement of an electromagnetic catapult for a driving linear motor, performing design on an overall structure of the linear motor; 2, establishing an air-gap field analytic model and a thrust model of an iron core-free permanent magnetic linear synchronous motor; 3, establishing a mathematical model of the linear motor under autonomous decentralized control; and 4, performing autonomous decentralization on controlled magnetic-motive force. The control method has the advantages that the efficiency of the linear motor is improved and the design and manufacture difficulty of the motor is lowered.

Description

technical field [0001] The invention relates to a control method of a linear motor, in particular to a control method based on a linear servo motor. Background technique [0002] The catapult was developed with the advent of the aircraft carrier. Its function is to shorten the running distance of the carrier-based aircraft and promote its catapult take-off. Compared with vertical take-off, rocket booster take-off, inclined board jump and other methods, the catapult take-off method does not have high requirements for carrier-based aircraft and has certain advantages. Since the 1920s, catapults have successively experienced various forms such as compressed air, gunpowder, rocket, electric, hydraulic and steam. At present, except steam catapults, other forms of catapults have been gradually eliminated due to the limitation of safety and ejection energy, and restricting the development and use of carrier-based aircraft. [0003] Some of the current catapults have some unavoida...
