      Induction Machine

      Jean Claude Alacoque Page(s): 1 - 64
      Copyright Year: 2013

      Wiley-IEEE Press eBook Chapters

      The chapter 1 describes a new dead-beat (one sampling time response) control law for three-phase induction machines, based on the motor discrete-time state-space equation system of non-salient pole machines, using the eigenvalues of the transition matrix. The algebraic calculation of the control voltage vector takes account of motor parameters, of stator current measures, of torque, rotor flux and stator current set-points, and of torque, voltage, flux and current limits. A real-time implementation of algorithms is proposed with a Kalman observer. The total uncoupling between torque and rotor flux controls is shown, as well as the torque accuracy and dynamics. The PWM and sampling periods can be chosen regardless of control law, in order to optimize inverter switching frequency and motor current shape factor. View full abstract»

      Wiley-IEEE Press eBook Chapters

      The chapter 2 describes the same new dead-beat control law for three-phase surface-mounted permanent-magnet synchronous motors (brushless), based on the motor discrete-time state-space equation system, using the eigenvalues of the transition matrix. The algebraic calculation of the control voltage vector, takes account of motor parameters, of motor current measures, of torque and current set-points, and of torque, voltage, stator flux and current limits. A real-time implementation of algorithms without position sensor, is proposed with a Kalmans observer. The total uncoupling between torque and stator voltage controls is shown, as well as the torque accuracy and dynamics. The PWM and sampling periods can be chosen regardless of control law, in order to optimize inverter switching frequency and motor current shape factor. View full abstract»

      Interior Permanent Magnet Synchronous Motor

      Wiley-IEEE Press eBook Chapters

      Chapter 3 describes the same new dead-beat control law for three-phase interior permanent magnet synchronous motors with armature reaction, based on the motor discrete-time state-space equation system, using the eigenvalues of the transition matrix. The algebraic calculation of the control voltage vector takes account of d-q axis motor parameters, motor current measures, torque, flux and current set-points, and torque, voltage, flux and current limits. The general algebraic solution for minimizing the current for a given torque is presented. A real-time implementation of algorithms without position sensor is proposed with a Kalman observer. The total uncoupling between torque and flux controls is shown, as well as the torque accuracy and dynamics. The PWM and sampling periods can be chosen regardless of control law, in order to optimize inverter switching frequency and motor current shape factor. View full abstract»

      Inverter supply - Lc filter

      Jean Claude Alacoque Page(s): 191 - 212

      Wiley-IEEE Press eBook Chapters

      The chapter 4 describes the dead-beat control laws, for damping the input filter capacitor voltage of a power inverter feeding an electrical motor, but also for limiting the power supply current. The algebraic calculation of the control current uses the transition matrix eigenvalues of the filter discrete-time state-space equation. It takes account of filter parameters, of capacitor voltage and line current measures, of voltage and current set-points, and of voltage and current limits. According to the system input variable number with respect to the number of variables to be controlled, an hybrid control is proposed. The filter control dynamics is shown and discussed as a function of the filter disturbance modes. View full abstract»

      Conclusion

      Chapter 5, in conclusion, analyses the main advantages of this dead-beat control compared to the other continuous and discretized control methods, during the process sizing, the bench tests, the commissioning and the duty operations. This rapid control, without overshooting or lagging, sets bounds with an observer prediction, to the electric variables without any discontinuity. It makes it possible to control the motor variables independently of each other and to minimize the inverter and motor losses by an independent choice of PWM. View full abstract»
