Abstract

To solve the problems of quality inconsistency of the aluminum alloy engine block

mathematical model with the characteristic of nonlinearity

strong coupling and uncertainty was established for the metal mold casting solidification process.The cloud model can realize the uncertain transformation between qualitative description and quantitative numbers and it is combined with PID control method to achieve the optimal temperature control in the solidification process.To test and verify the superiority of the control algorithm

the temperature control system experimental platform was established to compare tests among the manual operation

PID control and cloud model PID control algorithm.The experimental results reveal that the cloud model PID has an advantage of following ability and stability.
