The Research And Design Of Wave Controllable Pressure Alternating System Based On Fuzzy Adaptive PID Control

Pressure fluctuation test-bed is a typical kind of environment simulation equipment, which is widely used in the test of reliability and durability for the product of military, motors and aviation. The nonlinearity of pressure system is too strong to make the precision and stability meet the request and this problem prevents its further application. Thus, how to use process control theory to get the best performance has become one of the most difficulty issues.Based on the project of pressure test-bed for Shanghai Volkswagen Automotive., LTD, this thesis investigates the design and realization of pressure alternating system with fuzz adaptive PID control. The main contributions are listed as follows:1. We analyze the technical request of the system, propose the design scheme and discuss the details of the hardware design. The principle and...
