To control the vibration of launch guider effectively and improve firing precision of Multiple Launch Rocket System (MLRS),the vibration of launch guider controlled plan by using plush thrust force is researched and designed based on the firing dynamics theory and the control theory;the pulse firing controlled system with 128 channels in three direction (X/Y/Z) is designed and actualized based on PXIbus. The system is composed of the center control module, the communication module with multi-channels and the digital output in three direction control module mainly. Data received from measuring devices by many channels at the same time,the pulse firing commands generated and output in three direction can be controlled by the control system. The physical simulative results shows that the control system can receive and dispose the data for orientation of launch guider in many channels and control the pulse firing and output with many channels in three direction. So the system is very important to realize the technology for improving the firing precision of MLRS by controlling the vibration of launcher guider by using plush thrust force.
