The invention particularly discloses a human body movement simulation system and a control method thereof. The human body movement simulation system comprises a posture simulation device for simulation various posture states of the human body, a micro control device for controlling the system to operate, timing body movement and receiving, reading, judging and analyzing an operation instruction, a terminal device for presetting body movement parameters, sending an instruction and displaying feedback information, a power supply device for providing operation power for the system, a first driving device for driving the human body posture simulation device to rotate and move around a Y axis and a second driving device for driving the human body posture simulation device to rotate and move around an X axis. Thus, simulation on a single posture and multiple postures can be realized, simulation on continuous posture change movement can also be realized, and the posture detection accuracy and the working efficiency are effectively improved.
