Simulating a complete electric drive system requires software packages covering the fields of power electronics components and control engineering. The authors have developed a software package for the simulation and design of drive systems. The simulation system is easy to use and enables the engineer to transfer often used methods of the fields stated above to the work on screen. The system is helpful in assessing the feasibility of a drive system at an early stage of development. Standard circuits can be defined as a building block. It is therefore possible to simulate and analyze fairly complex systems. The software package equipped with a graphical user interface.<>

The authors introduce a procedure to determine the set of essential parameters of a robot manipulator dynamic model. Then they use the Lyapunov stability theory to construct an adaptive control algorithm based on the model containing only the parameters that belong to the determined set. The proposed control algorithm is computationally efficient and it requires neither inversion of the manipulator inertial matrix nor joint acceleration measurement. Asymptotic stability of the proposed control algorithm is proved.<>

The aim of this paper is to compare the performance of two indirect field oriented control schemes. In the first one, the Park components of the stator currents are controlled by two PI regulators, and in the second one, these currents are not directly controlled and there is no current measurement. It is shown that the sensitivity of the flux control to parameter uncertainties is generally smaller in the control scheme without current controllers than in the control scheme with current PI controllers, in spite of the fact the latter offers a more precise current control. It is also shown that the control scheme without current measurement allows to develop a fully digital implementation on low cost microprocessors. Experiments on a laboratory prototype confirm the good performance of this simplified control scheme.<>

The method for determination of an initial rotor time constant of a cage induction motor is presented. It consists of applying the step form voltage and measuring the responding current. After some simplifications the current response term becomes easy to analyze. At least two measuring points are necessary for determination of both stator and rotor time constants.<>

The author surveys the configuration, machine vision systems and driving control systems of three intelligent vehicles developed in Japan, and discusses the significance in automobile traffic of the future. The intelligent vehicle of AISI, MITI developed since the mid 1970s, has a machine vision system for obstacle detection and an autonomous navigation system based on dead reckoning on a compact car. The machine vision system is featured by real-time processing using hard-wired logic. The Personal Vehicle System (PVS), developed in the late 1980s by Fujitsu amd Nissan, is a comprehensive test system for a vision-based vehicle. The machine vision system captures lane markings at both road edges for lateral control. The PVS has another machine vision system for obstacle detection. An intelligent automobile, named the Automated Highway Vehicle System (AHVS), developed by Toyota is capable of lane-keeping using machine vision. The three vehicles drove at 10-60 km/h. The possibility of solution of automobile traffic problems such as traffic accidents, congestion, and pollution using intelligent vehicles is discussed.<>

The paper deals with the problem of graphical modelling of the activities of production systems with robots and manipulators. These models allow two kinds of examinations. The first one is aimed of the determination of the smallest number of elementary processing cycles of the entry of the robotic technological complexes (RTC) to ensure that no collision occurs in the course of the processing of two subsequent parts. The second task consists of examining the minimum number of elementary technological steps ( Delta t) necessary to process an individual part in the course of its passage through the RTC in the case that part X follows the preceding part Y at the entry of the RTC. The applied mathematical model is based on weighted Petri networks (WPN), introducing a transformed graphical model of the RTC, having been compiled initially at the level of elementary technological activities.<>

The article presents an educational and design tool that describes the application of market available, yet industry standard, computer aided engineering (CAE) software. The tool is used to simulate the generated waveform of different configurations of power electronic circuits used intensively in motion control and static power converters. Harmonic content is revealed for the various simulated power converter waveforms to provide a simple, yet effective guide for the designer to the optimal control strategy and filter specifications.<>

An improved version of transistor-based AC line conditioners is proposed. As compared to previously reported structures, it uses fewer standard transistor modules. This, in combination with less stringent gating requirements, improves the overall operating reliability of the system. In addition, it retains the same advantages such as sinusoidal input/output waveforms, fast dynamic response, and small input/output filters. The operating principle of the proposed structure is discussed and the voltage feedback loop design is analyzed. Results from a 25 kVA experimental set-up are provided for verification.<>
