Abstract |
|
|
| This paper implements nonlinear robust control for the asynchronous motor with iron loss, derives and establishes the
efficiency model for asynchronous motor with controllable power loss, and put forward to realize the accurate linearization of model
with controllable power loss and high-precision tracking and control of speed and flux linkage of rotor through the state feedback
precise linearization algorithm of MIMO system.The output of affine nonlinear system is tracked and controlled through the design of
nonlinear robust controller. The simulation results show that with this control method energy saving control of asynchronous motor can
be realized indirectly, so that the average power loss of the asynchronous motor significantly increases from 47.63% to 72.89%. This
provides a reference for the design of controller of multiple input multiple output nonlinear mechanical and electrical system in the
engineering. |
