The pulsation torque is a consequence of the non-sinusoidal flux distribution and due to interaction of the rotor's permanent magnets with the changing stator reluctance. The proposed control method is an estimator based. To ensure parameter convergence the Lyapunov direct method is used in the estimator design for the flux Fourier coefficients. A novel nonlinear torque controller based on the flux/torque estimate is introduced to reduce the influence of the flux harmonics. The influence of the cogging torque is considerably reduced at lower motor speed using the internal model principle and adaptive feedforward compensation technique. An overall control scheme and experimental results are also presented.","PeriodicalId":365390,"journal":{"name":"Proceedings of the 2001 IEEE International Conference on Control Applications (CCA'01) (Cat.

This is mainly due to the fact that the SCT is stated in an event based asynchronous setting whilst PLCs are signal based and synchronous. Based on Petri nets the PLC programming language, the sequential function chart (SFC), is an ideal choice for this transition. However, the transition requires detailed knowledge of how the PLC and SFCs work. We present different execution models for SFCs and compare them with the international standard IEC 1131-3.","PeriodicalId":365390,"journal":{"name":"Proceedings of the 2001 IEEE International Conference on Control Applications (CCA'01) (Cat.

The torque and stator flux controllers were designed taking into consideration a model of the machine in the rotating reference frame attached to the stator flux phasor. The electromagnetic torque and stator flux, are controlled by non-linear hysteresis controllers; their output signals are used for generating the control signals of the inverter based on a switching table.

For this purpose a classic PID-controller combined with mass and frictional feedforward is compared to (i) a PID-controller combined with a model-based friction compensation using the dynamic LuGre friction model and (ii) a gain-scheduled optimal PD-controller based on a polytopic linear model (PLM). The latter consists of a feedforward part and an optimal nonlinear feedback part. The controllers are compared to the classic PID-controller by means of experiments on a rotating arm subjected to friction. The performance for three third order point to point setpoints shows that the gain-scheduled optimal PD-controller outperforms the other controllers with respect to settling time and maximal error after setpoint. The tracking performance is comparable for the LuGre-based controller and the classic PID-controller where the tracking performance of the gain-scheduled PD-controller is limited.","PeriodicalId":365390,"journal":{"name":"Proceedings of the 2001 IEEE International Conference on Control Applications (CCA'01) (Cat.

Stability robustness is analyzed via /spl mu/-analysis and ad-hoc models are developed in that sense for the phenomena that are the main sources of uncertainties. It is shown that stability is guaranteed for every phenomenon considered separately, but stability region must be restricted when the system is subject simultaneously to several phenomena.
