[en] The automation control system of heavy ion collective accelerator prototype on-line with 1001 TPA-i computer was designed. The problem of system structure and finding dominant factors for control in optimization regime of electron capture on electron orbit is solved. The one extreme taks of extreme control was solved. The number of electrons on equilibrium orbit is optimized by direct search method with constant step of every control variable. The full scale range and size step on every control variable were defined experimentally. The programs of optimization and representation were written. The control system apparatus was designed in CAMAC standard
