自整定嵌入式運動控制模塊設(shè)計
[Abstract]:Linear motor has been widely used in many fields, such as logistics system, industrial equipment, transportation and civil and automation system. Linear motor has become a focus of attention. The motion controller of linear motor is a very important part of its performance. This paper aims at the development of embedded motion controller of linear motor. A complete design scheme of self-tuning embedded motion control module is proposed. The dynamic model of linear motor is established, and the off-line and on-line parameter identification algorithms are designed. The first-order LTI filter is used to reduce the influence of high-frequency noise. The constant and variable parameters are identified and verified in MATLAB/Simulink. In the design of control algorithm, nonlinear adaptive robust control algorithm is used to realize precise motion control, and on-line parameter identification algorithm is used to realize the self-tuning function of system parameters and controller parameters. Simulink is used to simulate the sinusoidal response and the reference trajectory response of design, and the proposed method is verified by C674 in hardware. 8 DSP chip is the core of the motion control processor, through the design of peripheral interface circuit, the motion control module of linear motor is built. The function debugging of each module is carried out, and the process of DSP program development is introduced in detail. Then the whole motion control program including PID and Adaptive Robust Control algorithm is compiled and debugged. The test results of the embedded motion controller of linear motor based on PID and ARC control algorithm are compared.
