摘　　要：针对 2 .4m风洞中具有同步协调控制要求的子系统的特点 ,为了解决具有大质量、大惯性、大负载、负载严重不等以及风洞运行过程中有强烈气动干扰等特点的系统的同步协调控制问题 ,设计了一种同步控制器和一种智能误差补偿控制器 ,提高了系统的抗干扰能力 ,使系统的同步协调控制指标优于设计指标。Considering the specific characteristic of the systems which need synchronization used in the 2.4m wind tunnel, the synchronization controller and intelligent error compensation controller have been designed in this paper. The results show that the strategies proposed in this paper can solve the non synchronizing control problems of the system,which has large mass and heavy load,the disturbed load of which varies with the change in Mach number and stilling chamber total pressure and is not equal seriously to every action.Actual results are provided to illustrate the high control accuracy, strong anti disturbance ability of the proposed control strategy and the synchronal accuracy is better than the designed.
