PURPOSE:To improve speed pattern follow-up performance by performing fuzzy inference based on two inputs, i.e., difference between a pattern speed and an actual speed and difference between a pattern acceleration and an actual acceleration. CONSTITUTION:A difference operating unit 13a operates the difference between a pattern speed Vo outputted from a speed pattern generator 11 and an actual speed Vd detected through a speed/acceleration detector 7 whereas a difference operating unit 13b operates the difference between a pattern acceleration alphao outputted from an acceleration pattern generator 12 and an actual acceleration alphad detected through the speed/acceleration detector 7. These two differences are inputted to a fuzzy control section 16 where fuzzy operation is carried out and a radio wave peak value command Imo is outputted through a limiter 17. When fuzzy inference is carried out based on two elements of speed and acceleration, an optimal current peak value command Imo can be obtained. According to the constitution, speed pattern follow-up performance is improved and a train can be controlled accurately according to a pattern speed. |
