Title: ADAPTIVE CONTROL OF HOT ISOSTATIC PRESSING (HIP) FOR METAL MATRIX COMPOSITE FABRICATION
Agency: NSF
Contract: N/A
Award Amount: $300,000.00
 

Abstract:

FABRICATION OF METAL MATRIX COMPOSITES (MMC) REQUIRES THE USE OF SOPHISTICATED MANUFACTURING PROCESSES. ONE SUCH PROCESS IS HOT ISOSTATIC PRESSING (HIP) WHICH IS BECOMING A KEY TECHNOLOGY FOR CONSOLIDATING MMC AIRFRAME STRUCTURAL PANELS FOR ADVANCED AIRCRAFT. THE OBJECTIVE IS TO DEVELOP A HIERARCHICAL TWO-LEVEL ADAPTIVE OPTIMIZING CONTROLLER USING TECHNIQUES OF MODERN CONTROL THEORY, SYSTEM IDENTIFICATION, AND NEURAL NETWORKS. THE LEVEL 2 CONTROLLER MINIMIZES THE ULTIMATE COST PER UNIT OF PRODUCTION AND THE LEVEL 1 CONTROLLER REGULATES THE HIP PROCESS TO ACHIEVE OPTIMAL TEMPERATURE AND PRESSURE PROFILES DICTATED BY THE LEVEL 2 CONTROLLER. RESEARCH INCLUDES: (1) A STATE-OF-THE-ART SURVEY, (2) IDENTIFICATION OF LEVEL 1 PROCESS MODELS FROM REAL DATA, (3) THE DESIGN OF AN ADAPTIVE MODEL PREDICTIVE CONTROLLER (MPC), (4) TESTING OF THE MPC CONTROLLER, AND (5) DEVELOPMENT OF ARCHITECTURE FOR THE LEVEL 2 CONTROLLER.
