Abstract:

To address distortion problems of auto parts during the fatigue test.According to the experimental data, the mathematical modeling is made. Based on the actual requirements an appropriate performance indicators is constructed and the use of the optimal control algorithm be realized system output to track the amplitude of the input optimal control law. Through the Matlab numerical simulation and real-time simulation of the optimal control algorithm.

Key words: fatigue test platform, electrohydraulic servo actuator, virtual instrument control interface, optimal control algorithm, amplitude track
