According to the characteristics of gust wind environment simulation in environmental simulation laboratory, an iterative learning self tuning PID controller is designed and developed. The controller optimizes the value set points sequence by iterative learning method. The system adopts PID self-tuning control strategy. The simulation and experimental results show that, with the two kinds of control methods, which can improve the system dynamic characteristic result from set point change, the effective control of the expected environmental parameters is realized. In iterative learning control function, especially for the simulation of the sinusoidal wind, the actual value can track the set value, and the control precision of wind environment simulation is guaranteed.
