Semi-physical simulation of an optoelectronic tracking servo system based on C MEX S functions
Juan Chen, Zhai Jun-hong · 2010
To the design of an optoelectronic tracking servo system, not only the reasonability of the control algorithm should be considered, but the cost and time as well. It is necessary to establish the simulation model for the system. Applying the C MEX S functions, we can build the every independent digital control modules in MATLAB/SIMULINK for the optoelectronic tracking servo system. In the paper, we apply the C MEX S function to the design of the practical optoelectronic tracking servo system. For the speed, position loop control and TV delay compensations; we test the method [1, 2]. The simulation results verify the theoretical analysis. Because C MEX S function has the features of fast execute speed, independently generated program, directly download to the hardwires, we can design and debug the digital control modules in MATLAB/SIMULINK and then transform and download directly to DSP processor.
