Design On Motion Control System Of The Moving Rope Vibration Experimental Device

Vibration is a common phenomenon in human production and life, vibration of moving rope gives us many problems, such as security problems caused by cable vibration, the transfer efficiency issues of vibration of power transmission belt, axial movement of the wire rope vibration has become a serious obstacle of the development of various technology, research on axial vibration response and characteristics of rope shift vibration of the system has important application value in the vibration and stability control engineering systems, in order to verify the correctness of the method used to establish the experimental system is inevitable after the theoretical analysis. This test system is controlled by the movement of two stepper motors by DSP, rope vibration in the vertical direction can be measured using non-contact displacement sensor directly.In hardware design, TMS320F2812is used in hardware circuit design of the stepper motor control system which includes power generation circuit, PWM signal generating circuit, serial communication interface circuit, encoder interface circuit and so on. In software design, it includes the communication module, data acquisition module, fuzzy PID control module, etc.To improve the performance of stepper motors, in this paper conventional PID control theory and modern fuzzy control are researched, accordingly this paper combines them organically, so it establisheds a fuzzy PID controller meeting the requirement of two-phase hybrid stepper motor control system, and gives fuzzy control rules table, which realizes the requirement of the motion control system, it also gives the simulation of control system established, and verifies that fuzzy PID is superior to the conventional PID.
