In a method for current regulation of permanently excited synchronous motors for guided missiles with an electromechanical actuating drive for the rudder, the commanded current is always guided orthogonally to the magnet-wheel flow. Further:a) from measured current of two voltage phases, a measured magnitude of a current-space pointer is determined and an error value for the current is added to a desired value of the amount via a correction regulator; andb) from measured current of two voltage phases as well as from the angle command of the current-space pointer, a measurement for the angle error is determined and added to the desired angle value via a correction regulator.The method according to the invention can be implemented with little hardware expenditure and in a compact design size, even for high rotational speeds of >10,000 min-1. Current-regulating methods used heretofore, which involve frequency response compensation in polar coordinates, cannot be used with synchronous motors, i.e. explicit determination of the angle of the space-current pointer fails in cases where the measured current disappears. |
