2. 1. Parameter estimation and model based control design of drive train systems

   Author : Mats Tallfors; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; control; drive train; estimation; identification; mechanical; Signalbehandling; Signal processing; Signalbehandling;

   Abstract : The main control task in many speed-controlled drives is to eliminate or reduce the load speed error caused by the load torque disturbance and reduce oscillations as quickly as possible. This thesis addresses different aspects of identification and control of such resonant elastic systems. READ MORE

4. 2. Drive train system dynamic analysis; Application to wind turbines

   Author : Saeed Asadi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind turbine drive train dynamics; Model validation; Global sensitivity analysis; Bearing defects detection;

   Abstract : To facilitate the design and production of highly efficient and reliable wind turbine drive trains, the project deals with the mathematical modelling and experimental study of drive train system dynamics.A typical drive train is considered as the subsystem of a wind turbine that transfers mechanical power from the rotor hub to the generator, and thereby plays an important role in the system dynamics and efficiency of wind turbine operation.

6. 4. Permanent-Magnet Synchronous Machines with Non-Overlapping Concentrated Windings for Low-Speed Direct-Drive Applications

   Author : Florence Meier; Juliette Soulard; Zi-Qiang Zhu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electronic engineering; electrical engineering; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Abstract :  Many geared electric drives can benefit from removing the gearbox and driving directly the load at low speed using a permanent-magnet synchronous machine (PMSM). PMSMs with non-overlapping concentrated windings are particularly attractive in low-speed direct drives since they allow, among other advantages, a high number of poles with a limited number of slots.
