Abstract
The present application provides a control system and method for a permanent magnet synchronous traction and transmission system. A The control system comprises a sampling unit and a controller; the sampling unit collecting an operation excitation current and an operation torque current, a input capacitor voltage and a rotor frequency; the controller acquires a target torque instruction issued to the traction and transmission system, calculates a target excitation current value and a target torque current value, and generates an excitation current regulation value and a torque current regulation value; a regulation unit is configured to generate a torque current regulation value according to the target torque current value and an operation torque current value and generate a target modulation ratio and a modulation frequency according to the excitation current regulation value and the torque current regulation value output from the regulation unit and finally output a PWM modulation wave control signal.
