Embodiment Construction
[0023] In order to be compatible with different characteristic requirements of position accuracy and velocity accuracy, a control strategy and control method with excellent performance is needed. Seamless switching mainly solves the control problem of multi-mode (position and speed), high precision and wide speed. Seamless switching technology includes: smooth switching between high speed and low speed under the condition of ensuring speed accuracy; good switching between operating modes (position, speed, servo) according to the test requirements of inertial devices.
[0024] In recent years, the functions of test instruments have been continuously expanded, which puts forward higher requirements for the adaptability of its control system. It creates conditions for the use of complex control strategies in the design of multi-parameter instrument control systems, and then provides a basis for the design of complex control strategies.
[0025] The principle of the invention is ...
