This paper presents a designing method of fuzzy control systems based on mixed programming of MATLAB and VC++ to realize the visual online modifying of the fuzzy control system and the algorithm of C code generating automatically by MATLAB/fuzzy control toolbox and MCC compiler. The codes are compiled into dynamic link library files to realize the seamless combination with the numerical control system of the original machine. This method implemented controller algorithm generated rapidly and avoided possible mistakes in the generating process from algorithm to code. This paper performed experiments on a self-designed EDM machine with a fuzzy control system and the results have shown the validity of the EDM fuzzy control system.

The root lock mechanism is a key component of the space deployable mast. Reliability of movement of the root lock mechanism affects directly completion of function of the mast. At first, scheme of the root lock mechanism is analyzed and the mechanism is simplified into two-slider mechanism with a spring. Then movement of the mechanism is studied, and the method of multi-body dynamics of Roberson-Wittenburg is adopted to set up its dynamical equation. In preprocess, incidence matrix, path and circuit matrixes, and general coordinates are set up. In setting up dynamical equation, virtual power is adopted. At last, program in Matlab is used to check correctness of the movement of the root lock mechanism and confirm values of its structural parameters. After such analysis, rationality and correctness of the design are improved.
