Abstract

An executor input saturation control method of an automobile active suspension system relates o executor input saturation control methods. The executor input saturation control method of the automobile active suspension system mainly solves the problems that existing design models are too simple to meet the requirements of executor saturation control of automobile suspension systems or cope with the influence of uncertain parameters and comprises the steps such as, firstly, establishing a nonlinear uncertain time-delay active suspension system model; secondly, deducting a self-adaption back stepping recurrence controller based on an instruction filter; thirdly, adjusting control gain parameters of the self-adaption back stepping recurrence controller. The executor input saturation control method of the automobile active suspension system is applicable to the field of automobile active suspension control.

Description

technical field

[0001] The invention relates to an actuator input saturation control method. Background technique

[0002] Active suspension systems play an important role in the automotive industry. A well-designed suspension system can not only improve the comfort of the driver and passengers (isolate the body vibration transmitted from the irregular road surface to the driver and passengers), but also have good grip. Today's active suspension system has been widely used in the automotive industry because of its advantages such as light weight and small size. In the active suspension system, actuators such as motors or hydraulic systems are usually placed between the frame and the vehicle body to stabilize the posture of the vehicle body and improve driving comfort by dissipating and increasing the disturbance energy of the system.

[0003] However, while we enjoy the advantages brought by the control of the active suspension system, the possible actuator saturation prob...
