   Application of Adaptive Neural Controller and Filter Tune for Multi-Mass Drive System
By Tomasz PAJCHROWSKI [View]
[Download]

Abstract: The article presents a comparison of dynamic properties of adaptive neural controller for the system with a complex mechanical structure and variable moment of inertia. Due to presence of several mechanical resonances (since it is a multi-mass system) at higher frequencies two filters were implemented: a simple LPF (Low Past Filter) and Fixed Filter, taking into account the changing parameters. A suitably tuned speed filter is applied to the feedback loop in order to damp the selected resonance frequencies In the paper was placed a results of simulations and laboratory tests with PMSM motor for the multi-mass system of variable parameters

   Design of High Flux Density Active Magnetic Bearings for High-Speed Multi Megawatt Motor
By Rafal JASTRZEBSKI [View]
[Download]

Abstract: This work studies active magnetic bearings design alternatives for a contactless operation of high-speed multi megawatt solid rotor induction motor. Different actuator geometries, employment of flux barriers, use of rectangular multi-step wound coils, alterations in winding schemes, and comparison of silicon steel sheets with cobalt-iron sheets in AMB design are examined. Minimum space, maximum capacity, electromagnetic operation at high-speeds, and bandwidth requirements are discussed. Functional comparison of selected geometries is presented based on FEM results. Lookup table based electromagnet model suitable for control design verification is disclosed.

   Design of Magnetic Couplings for Bioreactors: Analytical Treatment and Optimization
By Svetlana ORLOVA [View]
[Download]

Abstract: In this work, investigation of magnetic couplers used in industrial applications such as bioreactors for mixing of liquids has been performed. Nowadays, the best solution as to contamination problems associated with mixing in stirred tank bioreactors is magnetic coupling. In this investigation, analytical treatment was carried out for the factors affecting the value of critical torque. These are: materials of the main design details, permanent magnet (PM) shape, PM width and height, the number of pole pairs, and the air gap. In the framework of investigation, design improvement and optimization were performed for 1 m3, 4 m3, 15 m3 magnetic couplings (JSC 'Biotehniskais Centrs' production). The results of numerical modelling were compared with those obtained experimentally.

   Evaluation of Accelerometer Control Interface with Powered Wheelchair
By Alexander BUBOVICH [View]
[Download]

Abstract: This paper deals with the problem of control of the wheelchair by people, who either is not able or have difficulties with moving and mechanically interacting with objects using their limbs (due to some kind of nervous system disease or trauma). There are different ways, how to receive data from that kind of patient, for example, electroencephalography, myoelectric interface, or accelerometer plus gyroscope interface. It was chosen to test one type of powered wheelchair control interface - accelerometer interface. For this purpose, conventional joystick interface was replaced with accelerometer interface, where two accelerometers are used to control wheelchair - one accelerometer is used to control the wheelchair's movement, the other one is used to measure the momental speed of the wheelchair. In the wheelchair two DC motors were used, to control them a workbench with two H-bridge motor control shields was developed.

   Improvement in Control Performance of PMSMs by Deactivation of Antiwindup Control in the Overmodulation Range of an Inverter
By Yosuke NAKAYAMA [View]
[Download]

Abstract: This paper proposes a current control system which deactivates an antiwindup control for improving the control performance of PMSMs in the overmodulation region of an inverter. Control performance of PMSMs cannot be improved appropriately without countermeasure against harmonic components which are generated in this region. Deactivating of antiwindup control can be a countermeasure against these harmonic components, however deterioration of current responses due to windup phenomenon is unavoidable. Proposed control system reduces the deterioration of torque response due to windup phenomenon by deactivating the antiwindup control only in the steady state in the overmodulation region. Proposed control system have con_rmed that it can achieve fast torque response and high power operation by simple algorithm without motor parameters.

   Position Sensorless Control based on Pattern Matching Method using Multiple Template Data Sets to Improve Position Control Error
By Hamin SONG [View]
[Download]

Abstract: This paper presents a position sensorless control scheme based on pattern matching method for high power density Interior Permanent Magnet Synchronous Motors (IPMSMs) that have non-sinusoidal in-ductance spatial distribution. The pattern matching method achieves the closed loop position sensorless control under heavy load condition. However, atypical position control control errors are generated. To improve the position control errors, a new pattern matching method is proposed in this paper. The proposed method estimates the rotor position by using multiple template data sets which created while changing a current phase. Through experimental results, the effectiveness of the proposed method is presented.

The proposed method is constructed based on 'Ld$ model', which is a robust mathematical model designed to address magnetic saturation in IPMSMs. Therefore, the proposed method has robustness to magnetic saturation.

   Real-time position control in permanent magnet synchronous machine drives
By Sabin Constantin CARPIUC [View]
[Download]

Abstract: A challenging problem in permanent magnet synchronous machine (PMSM) drives is position control in the presence of unknown disturbances. This paper proposes a low-computational-complexity cascade control structure for position control in PMSM drives. Model-Based Design is used to create an optimal controller in the error space of the outer loop of the cascade control structure. A state and disturbance observer is employed to estimate the load torque of the drive. A PI-based control algorithm is used in the inner current control loop. This paper presents real-time simulation results of the cascade control and PMSM drive model using a Speedgoat Performance real-time target machine. Finally, it compares those results to results obtained by using a traditional PI control approach.
