Abstract

The invention discloses a torque and inertia dual-changeable apparatus for a permanent magnet alternating current servo system and a control method for the torque and inertia dual-changeable apparatus. The torque and inertia dual-changeable apparatus comprises a permanent magnet synchronous motor, speed reducers, a magnetic powder brake, a magnetic powder clutch, a coupler, a thrust ball bearing, a small motor, a module and a sliding block. Load torque on the output shaft of the permanent magnet synchronous motor is controlled by excitation current of the magnetic powder brake so as to realize sudden change of torque; sudden change of inertia is realized by controlling the separating and combining of the magnetic powder brake; by controlling the position of the sliding block in an inertia plate, the mass distribution of the inertia plate is changed, and multimode gradual change of the inertia is realized; and by adoption of the torque and inertia dual-changeable apparatus, sudden change of the torque of the servo system can be realized, and sudden change and gradient change of the inertia also can be realized.

Description

[0001] 【Technical field】 [0002] The invention relates to a double-variable torque inertia device of a permanent magnet AC servo system and a control method thereof, belonging to the technical field of electromechanical control. [0003] 【Background technique】 [0004] Since the permanent magnet synchronous motor has the advantages of high power density, high efficiency, high reliability, simple structure, small size and light weight, it can meet the requirements of high-performance systems, such as fast dynamic response, wide speed range and high power factor, etc. Therefore, it is widely used in popular fields such as industrial robots, CNC machine tools, and aerospace. A high-performance AC servo system not only requires the system to respond quickly to servo instructions, but also requires the system to be robust when external disturbances or load object characteristics change, which requires the controller structure of the servo system and Controller parameters can be pr...
