Method for optimizing relay pedestal quality based on improved type SPSA

Abstract

The invention relates to a method for optimizing relay pedestal quality based on an improved type SPSA. The method is executed through a relay pedestal quality optimization system. The system is connected with an injection moulding machine through a data communication port and comprises a detection unit and a host. The host comprises an initialization module, an optimization module, a preprocessing module, a postprocessing module and an optimization process estimation module. The method comprises following steps that the detection unit carries out quality detection on the relay base produced by the injection moulding machine; a detection value is transmitted to the host through the data communication port; the host carries out estimation on optimality of parameters of the group; an iteration technology parameter combination of the next step is given out by the optimization module; the parameter combination is transmitted to the injection moulding machine through the data communicationport for carrying out online experiments; and the iteration of the above processes is performed until a proper optimal technology parameter combination is found. According to the invention, the implementation cost is small; optimization time is saved; and experiment cost is reduced.
