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.

Abstract: The present disclosure relates to a flame retardant composed of multi-component phase change material particles. These particles consist of paraffin wax, nano-flame retardant, and conventional flame retardant. The phase change material is modified with nano-flame retardant and physically coated with conventional flame retardant. The multi-component phase change material flame retardant is formed by creating a two-layer nucleus-shell structure. The nucleus core is made up of the conventional flame retardant, while the shell layer is composed of the nano-flame retardant doped phase change material. The multi-component flame retardant material combines the performance advantages of phase change material, nano flame retardant, and conventional flame retardant. The combination of nano flame retardant and phase change material weakens the disadvantages of phase change material and allows for the full utilization of the energy storage capabilities of the phase change material.
