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.
