STATIC OUTPUT FEEDBACK CONTROL METHOD FOR FORKLIFT STABILITY CONTROL, AND STORAGE MEDIUM

WIPO Patent Application WO/2023/236786

A1

Disclosed in the present invention is a static output feedback control method for forklift stability control, and a storage medium. The control method comprises: setting a fuzzy system model, a singular observer module, a generalized observer module, a residual generator module, and a static output feedback control method module for forklift stability control. The singular observer simultaneously estimates the state and fault of the system. The generalized observer is used for generating a residual signal which is sensitive to disturbance as much as possible and insensitive to disturbance. The residual generator reduces the sensitivity of the system to disturbance to the maximum extent, while improving the sensitivity to faults to the maximum extent. The static output feedback control method for forklift stability control uses measurable signals such as a fault and state provided by an observer, so as to control a dynamic system. In the present invention, after a system fault, the reconfiguration of the control law can be ensured on the basis of an estimation state and a fault vector, performance before the system fault is recovered as much as possible, and the transverse stability and the active safety of the forklift are greatly improved.
