Abstract
The design is that armature is reversible , rotational speed and current the two pressure regulating speed adjustments of closed circuit of direct current system. the loop of magnetic field adopt bridge-type rectification circuit, armature loop adopt may control silicon three-phase bridge-type rectification pressure regulating system, switch with contactor current with realize reversible operation. this systematic application project design two current regulators and the rotational speed of method design adopt PI structure , with realize stable state have no static difference; at the same time lead into the differential negative feedback of rotational speed on the regulator of rotational speed, have so reached restrain the purpose of the super tune of rotational speed. use MATLAB/SIMULINK finally emulate for system analyse and rectify , is systematic parameter further optimization and the debug on-the-spot have established foundation.
Key words: the two systems of closed circuit of direct current of speed adjustment; armature reversible; the emulation of MATLAB/SIMULINK
