This paper presents some specific issues of a high speed permanent magnet synchronous motor control used in a combustion engine supercharger system. A description of a method designed to limit the load angle of synchronous motor in high speed is given. Also experimental results in dynamic states are shown. In these states mainly acceleration times and energy intensity with correlation on motor current and field weakening were examined. Dynamic properties were tested for a power supply with both high and low internal resistance. The experimental setup description is given and test results for speed up to 42 000 RPM are shown.

Operating Systems of Embedded Devices can manage application data more effectively. This directed us to consider a new dynamic memory management approach for GPS and similar embedded systems. The uniqueness of the suggested approach is shifting elements of the application to the Operating System with the aim of manage application data more effectively. A key component of an application is caching its data with the purpose of preventing excessive memory accesses and allocations. The suggested approach called “Cache Based Dynamic Memory Management” - CBDMM proposes to move the caching component from the application to the Operating Systems. We present CBDMM design, discusses its advantages and show encouraged benchmarking results.

KNXnet/IP system allows integration of different KNX networks through an IP network, used as fast backbone. Integration is realised by a particular device called KNXnet/IP Router. Due to the very limited transmission speeds foreseen for the KNX networks, the KNXnet/IP router may represent a bottleneck in routing telegrams coming from the IP network whose destination is a KNX device located in the relevant KNX network. The aim of the paper is to analyse the effect of congestion of KNXnet/IP Routers on the information flow between KNX devices attached to different KNX networks through an IP backbone.

This paper presents a hybrid modeling method for a pneumatic artificial muscle that vertically suspends a mass. The modeling mainly consists of mechanical and hydrodynamic equations and is developed with empirical modifications. A feature of this approach is that it allows the model to include if-then formulation and nonlinearity such as flow dynamics and friction. And the model includes a novel mass flow model which allows the mass flow rate to converge to zero in steady-state operation. Furthermore, in order to show validation of the obtained hybrid model using a practical testbed system of the PAM we made.

This paper introduces an adaptive DC bus voltage control strategy for renewable energy systems, combining different energy storage devices, i.e., batteries, fuel cells, and supercapacitors. Multiple bidirectional DC-DC converters accurate control is achieved with no source voltage sensing, which reduces the number of sensors. Unlike many adaptive controllers, the proposed strategy uses a single adaptive parameter, which yields reduced complexity. The proposed approach is compared to a classical PI-based cascaded control scheme. The adaptive control strategy achieves better performance, which yields a high-efficiency operation of the overall system.

This paper proposes a dual current-slope rotor position estimation and its relative sensorless closed-loop drive system for synchronous reluctance motors. First, the mathematical model of the synchronous reluctance motor is discussed. Then, a new rotor position/speed estimator of the synchronous reluctance motor is proposed. The proposed method uses dual current-slope to estimate the rotor position and rotor speed for a synchronous reluctance motor. In addition, the estimator can easily be realized and is unrelated to the motor parameters. The estimating technique does not require any extra hardware circuit when compared to the traditional drive system. A TMS-320F-28335 digital signal processor is used to execute the rotor position/speed estimation, the position or speed control algorithms, the d-q to a-b-c coordinate transformation, and the PWM switching strategy. The hardware circuit, therefore, is very simple. Several experimental results are provided to validate the theoretical analysis.

Radial basis function neural networks (RBFNN) are used to dynamically identify harmonics content in converter waveforms based on p-q (real power-imaginary power) theory. The converter waveforms are analyzed and the harmonic contents are identified over a wide operating range. The proposed RBFNN filtering training algorithm are based on systematic and computationally efficient training method called hybrid learning method. The small size and the robustness of the resulted network reflect the effectiveness of the proposed algorithm. The analysis is verified using MATLAB simulation.

The digital revolution and faster switching devices have introduced more sophisticated control systems that require high quality and reliable operation. The rapidly growing demand for alternative/renewable energy generation systems and use of energy sources on a large scale, require new technologies. In this paper, a novel renewable energy conversion system, which has the reduced number of switching elements preserving the same power conversion functionality is proposed. The proposed multi-mode energy conversion system is able to supply energy from multi-sources (renewable energy source, battery, and ultra-capacitor) to a load and store energy with the minimum number of switching elements. The proposed approach is verified both by simulations and experiments. The results will enable more timely and wide usage of alternative/renewable energy systems resulting in increased energy security.

In this paper, an adaptive PID-Fuzzy Logic controller is proposed in order to control the angular displacement of an automobile Pierburg mechatronic actuator and achieve a wireless network control. This new PID-fuzzy logic controller topology takes advantage of the classical PID controller and the fuzzy logic technique which can improve the angular displacement precision and reduce the time delay caused by the wireless communication in the control loop. Different from other fuzzy PID controllers, our PID controller is located before the fuzzy controller and acts as its inputs. A mathematical analysis and the advantages of the designed controller are discussed. The proposed PID-Fuzzy Logic controller achieves the control task reducing the steady-state error and the time delay. Experimentation results of the wireless control are presented exhibiting good performances.

The computational cost of the dynamic equations is very important in real time control applications of industrial robot manipulators. Basically, the computational cost depends on the joint properties, the method used for deriving the dynamic equations and the algorithm efficiency. In this study, the dynamic equations for the sixteen three and six degrees of freedom fundamental robot configurations were derived using Newton-Euler (N-E), Lagrange-Euler (L-E) and Hamiltonian (H) methods in symbolic form. The computational costs of these dynamic equations for both three and six degrees of freedom manipulators are obtained. Some comparisons considering the joint properties, the method and the workspace geometries of the manipulators are performed and some important conclusions are summarized.
