摘要： In a process for controlling a rotating machine having n phases powered by a voltage inverter defining m.sup.n states of the stator phase voltage vector the electromagnetic torque .GAMMA. and the stator flux .vertline..phi..sub.s .vertline. of the machine are servocontrolled. A calculator calculates a succession of n states of the phase voltage vector to move the torque .GAMMA. and the flux .vertline..phi..sub.s .vertline. towards the set points .GAMMA..sub.ref, .vertline..phi..sub.s .vertline..sub.ref. On each sampling, the calculator calculates the remaining application time of the current state and the updated application times of the future states of the phase vector. Asynchronously with the sampling times and the calculation times, the calculator sends SPmLL switch control signals to switch from the current state to the next state.

摘要： A method is described of regulating the instantaneous electromagnetic torque of a polyphase rotating electrical machine equipped with stator and/or rotor windings supplied by a voltage and a current generated by an inverter formed of switches whose switching is controllable. The method comprises a step of commanding the switching of the switches of the inverter using the fundamental frequency of the voltage generated by the inverter and a form of synchronous pulse width modulation configured as a function of an input set point, and a step of calculating the input set point from an instantaneous torque set point at each regulation time. The method further comprises a step of determining the time interval between two successive regulation times so that the time interval corresponds to an integer multiple of the period of oscillation of the instantaneous torque of the machine.

摘要： Method and device for controlling the angular speed of an electromechanical drive train with little damping. The control of the speed of the load driven in rotation by an electromechanical drive train with little damping, possibly having transmission nonlinearities such as play, without measuring said speed, is accomplished by using an observer in conjunction with a robust CRONE-type non-integer order controller, the physical realization of which is achieved by an integer order controller obtained by approximation in the frequency domain. The device thus provides good damping for the system in the presence of resonance frequencies and excellent robustness, while still allowing a relatively simple adjustment.

摘要： A method of controlling the torque of a rotary machine powered by means of an inverter and servo-controlled by a system having sensors, an observer, and a computer which delivers controls to the switches of the inverter on the basis of values supplied to the observer by the sensors, in the form of sequences of three vectors to bring the torque &Ggr; and the stator flux &PHgr;S of the machine towards reference values for &Ggr;ref and &PHgr;Sref. The measurement sampling period is selected to be equal to the sequence period DTML which corresponds to half the switching period of the inverter. The characteristics of the vectors for each sequence are obtained by solving the following system of equations: &AutoLeftMatch; ( ⅆ Γ ⅆ t a t a + ⅆ Γ ⅆ t p t p = Γ ref - Γ n t a + t p = DTML in which d&Ggr;/dta and d&Ggr;/dtp are variations over time in torque respectively when an active vector Va or a passive vector Vp is applied, &Ggr;n being the present torque, and ta and tp are the respective times during which the vectors are applied.

摘要： A method of regulating a rotating electrical machine includes a preparatory step of determining a discrete voltage control law for the machine. The discrete control voltage to be applied at each sampling time is determined in the form of a first term corresponding to free evolution of the state of the machine in the absence of control, between the preceding sampling time and the current sampling time, and a second term dependent on the set point torque and a set point for the magnetic energy consumed by the machine. The method further includes, at each sampling time, a step of determining, with the aid of the discrete control law, the control voltage to be applied to the machine for the torque of the machine to reach the set point torque and the magnetic energy consumed by the machine to correspond to the set point magnetic energy.
