Abstract-This paper deals with model-based two-degrees-offreedom (2DOF) speed control of two-mass systems. An analytic gain selection of a proportinal integral (PI) type feedback controller is proposed. The gains are given as functions of system parameters and desired dominant closed-loop poles. An analytic design of a prefilter is given to complete the 2DOF structure, using the pole-zero distribution of the feedback loop. The prefilter design covers step, ramp, and parabolic reference tracking. The proposed 2DOF controller is evaluated by means of simulations and experiments. The experimental setup consists of two 4-kW servo motors coupled together with a toothed belt. It was found that the proposed controller gives good reference tracking for step and dynamic commands as well as robust and fast loadtorque rejection.

Abstract-The paper deals with the application of forced dynamic control strategy in the two-mass resonant system. First the basic of the forced dynamic control theory in the case of the drive system with elastic coupling is presented. The analytical equations which allow for calculating the control structure parameters are given. The included simulation results confirm the effectives of the proposed control In order to applied the proposed control structure the information about non-measurable states is necessary. So general description of the extended Kalman filter is presented.Simulation results were confirmed experimentally in the laboratory set up.

Design and Evaluation of a Multi-layer Interior PM Synchronous Motor for High-Speed Drive Applications

In general, surface mounted PM synchronous motors (SPMSMs) are mainly adopted as a driving motor for high-speed applications, because they have high efficiency and high power density. However, the SPMSMs have some weak points such as the increase of magnetic reluctance and additional losses as a consequence of using a non-magnetic sleeve. Especially, the magneto-motive force (MMF) in the air-gap of the SPMSMs is weakened due to the magnetically increased resistance. For that reason, a large amount of PM is consumed to meet the required MMF. Nevertheless, it cannot help using the sleeve in order to maintain the mechanical integrity of a rotor assembly in high-speed rotation. Thus, in this paper, a multi-layer interior PM synchronous motor (IPMSM) not using the sleeve is presented and designed as an alternative of a SPMSM. Both motors are evaluated by test results based on a variety of characteristics required for an air blower system of a fuel cell electric vehicle.
