Abstract. In order to improve the efficiency of identifying
parameters using the maximum likelihood method and to avoid the sensitivity of initial
values, a proposed method that combines the micro-genetic algorithm with the advance and
retreat method is presented in order to identify the eccentricity of the spindle-tool
system with random input and output parameters, which obey a
certain probability distribution. Eccentricity without prior information
is determined through an iterative procedure. The initial value starts from
zero, and the interval is determined by the advance and
retreat method. Then, the optimal value is searched in the corresponding interval,
utilizing the micro-genetic algorithm. The initial value and interval at each of
iterations are changed to ensure a fast and stable convergence. Eventually, a
numerical example with three kinds of random deviations verifies the
feasibility and validity of the proposed method.
