AI Technical Summary
In the existing design and optimization process of piezoelectric nozzles, there is a lack of precise and systematic sampling methods, resulting in inconsistent sampling data quality and limited coverage, which affects the accuracy and stability of the optimization results.
A voltage pulse sequence injection control method using a fully digital piezoelectric nozzle is proposed. By inheriting the Latin hypercube sampling method and the Kriging approximation model, a global sensitivity analysis matrix is constructed. Combined with fast Fourier transform and second-order difference screening, the voltage pulse sequence control strategy is optimized to achieve fully digital injection control.
It improves the accuracy and stability of injection control, shortens the development cycle, reduces experimental costs, and enables flexible adjustment of control strategies under different injection requirements and environmental conditions, thereby improving injection performance and reducing energy consumption.
