Title:
NONLINEAR ANTI-INTERFERENCE CONTROL METHOD AND APPARATUS FOR ELECTRONIC THROTTLE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/062499
Kind Code:
A1
Abstract:
Disclosed are a nonlinear anti-interference control method and apparatus for an electronic throttle system (100). On the basis of a system control model and a continuous limited time anti-interference control method, a control apparatus is designed in response to a tracking and control problem of the degree of valve opening of an electronic throttle (104), and a design method therefor is provided. An observation method and apparatus are designed in response to multi-source interference, uncertainty and nonlinearity caused by factors, such as an inlet airflow, friction, spring torque and a tooth space, and the accurate estimation of lumped interference and a system state variable is realized within a limited time. A continuous terminal sliding-mode control method is combined with an output feedback control method, thereby effectively suppressing the adverse effects of multi-source interference, uncertainty and nonlinearity in the electronic throttle system (100), such that in the case of a system being subjected to interference, accurate tracking and control of the degree of valve opening of the electronic throttle (104) is realized within a limited time; meanwhile, the hardware costs of the system are reduced, and the dynamic characteristic, steady-state characteristic and anti-interference capacity of the system are improved.
