Abstract

The invention provides a dynamic performance debugging method and system suitable for a servo system. The method comprises a step of debugging and confirming the property of matching between a servo controller and a motor and the correctness of three phases of the motor, a step of confirming the correctness and accuracy of a sensor, a step of confirming the property of matching between a three-phase current and a rotary encoder and an initial angle of the rotary encoder, a step of controlling a current loop, a step of confirming the correctness of a motor speed solver, a step of controlling aspeed loop, a step of controlling a position loop, a step of realizing control instruction, parameter binding and telemetry message protocol communication, a step of enabling the servo system to havethe predetermined dynamic response performance, and a step of enabling the load servo system to have the predetermined dynamic response performance. Debugging under a load condition can be carried outin a realest environment, so that a simulation link is reduced; a high-power electromagnetic environment can be included; various parameters of the system are most accurate; and at the moment, the optimal dynamic performance of the servo system can be obtained.

Description

technical field [0001] The invention relates to the field of electric servo systems, in particular to a dynamic performance debugging method and system suitable for servo systems, especially a dynamic performance debugging method for high-power servo systems. Background technique [0002] With the development of the motor industry, more and more servo drive systems use electric instead of hydraulic. In the launch vehicle field of aerospace engineering, the volume and weight of the servo system have strict restrictions, and the electric servo system has been widely used. In the high-thrust launch vehicle, a high-power electric servo system is required to control the swing of the engine, and the servo system is required to have high dynamic response capability. Electric servo system mainly includes servo controller, servo motor, servo mechanism, power supply, control and communication software, etc. The working process of the entire electric servo system can be described as:...
