  • Publication number: 20250004431
    Abstract: The invention discloses 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, a static output feedback control method module for forklift stability control. The singular observer estimates the state and faults of the system simultaneously. The generalized observer is used to generate a residual signal that is as sensitive as possible to faults and insensitive to disturbances. The residual generator minimizes the system's sensitivity to disturbances while maximizing its sensitivity to faults. The static output feedback control method for forklift stability control uses measurable signals such as faults and states provided by the observer to control the dynamic system.

  • Publication number: 20240416881
    Abstract: A forklift active braking control method based on power shift transmission, comprising the following steps: step 1: obtaining forklift state parameters, if the current state of the forklift is an active braking state, performing step 2; step 2: inputting a current speed signal of the forklift, and obtaining duty ratio parameters that are impact-free and can produce a maximum braking force at the current speed, and outputting proportional solenoid valve control parameters of the transmission according to the obtained duty ratio parameters; step 3: using the proportional solenoid valve control parameters to control the proportional solenoid valve of the transmission to take action, and controlling the forklift power system to output a driving force opposite to a current movement direction of the forklift to drive the forklift to actively brake; step 4: exiting the active braking of the forklift when the forklift speed is detected to be zero.
