Results of computer simulations of motion cotrol problem of an inverted pendulum to swing up and to stabilize in inverted state were presented. Calculations were carried out using genetic algorithm to find time-sequential signals to swing up an pendulum from pendent state and to stabilize it in inverted state. Individual genome consist of four locuses, four time intervals for bang-bang control principle to swing, and four gains for states feedback control to keep standing were developed in evolutionary computation with evaluating cost function as sum of deviations from final state to be minimized. Obtained control signals were good compared to optimized one derived by trial and error method.
