发明名称 Control process for a rotary machine, servosystem for carrying out this process and rotary machine with such a system
摘要 The procedure provides control of the rotating electrical machine (1) with n phases supplied with alternating current via a voltage oscillator (3) comprising n SPmLL (Single Pole m Logic Level) devices (4). These define m<n> states (Vi) of the stator phase voltage vector (Vs). The machine has an electromagnetic couple (Tem) and a stator flux (ph-s) controlled by reference values of electromagnetic couple (Temref) and stator flux (ph-sref). For a transitory regime, in which the electromagnetic couple and/or the stator flux are far away from the reference values, a choice is made from the possible values (Vi), of the stator phase voltage (Vs) in order to identify the optimal value to bring these values back towards the reference values. The switching of the SPmLL devices (4) is controlled in a manner corresponding to the state chosen for the stator phase voltage vector.
