| 英文摘要 |
| Aiming at the problem of low control accuracy caused by the nonlinearity and disturbance of the electronic
throttle valve, this paper proposes a novel discrete high-order sliding mode controller. Firstly, the Euler discrete method is
used to establish the electronic throttle discrete model. Based on the discrete time high-order sliding mode theory, a multi
step recursive reaching law is proposed. In order to take into account the convergence rate and steady state accuracy, the
nonlinearity switching gain is used instead of the traditional fixed gain, so that the steady state switching gain can maintain
the minimum level; At the same time, based on the disturbance estimation method with delay step size, the unknown
disturbance of the system is estimated, so that the sliding variable satisfies the high-order accuracy of the sampling step size,
and the discrete fast terminal high-order sliding mode controller is designed in combination with the proposed reaching law.
Then the stability of the closed loop system is theoretically analyzed, and the steady state accuracy of the sliding variables
and tracking errors of the system is calculated. Finally, two experimental test schemes are designed, and the proposed
controller is compared with active disturbance rejection controller and two common discrete sliding mode controllers. The
experimental results show that the proposed controller has better performance in disturbance resistance, continuity and
tracking accuracy. |
