HOMER is a voice-driven text-to-speech system developed for blind or visually impaired persons for reading the Slovenian texts. Users can obtain texts from the special corpora organised on the computer network server at the information centre of the Association of the Slovenian Blind and Visually Impaired Persons. The system consists of three main modules. The text-to-speech module enables speech synthesis from an arbitrary Slovenian text input, the speech recognition module performs speaker independent isolated word recognition and the dialogue module controls the different tasks of the HOMER system and obtains texts from the source text corpora. Presently, the system runs under Linux and requires a Pentinum/133 PC with minimum 32 MB of RAM and an additional standard 16 bit sound card.

For calculation of the steady-state and dynamic characteristics of the electrical drives with induction motors and voltage source inverters, that have the control systems, in which the method of the motor torque direct control is utilized, a simple discrete model is proposed. Employment of this model gives an essential computation time saving with keeping of a good accuracy of results. The results of computation of the electrical drive characteristics, that are received both by simulation of the full drive equations and by using of the proposed simple model are given. These results show the validity of the proposed model.

Traditional linear control strategies are usually straightforward and easy to implement, but they tend to be helpless when dealing with complex nonlinear problems, which drastically limit their scope of application. In order to find a way that can overcome their drawbacks while not giving up their main feature of simplicity, this paper introduces evolutionary programming as an optimization method, which tackles the difficulty by being integrated with conventional PID controllers to form self-adaptive control systems. This approach has both the advantages of flexibility and simplicity, without sacrificing accuracy. A CSTR (continuous stirred tank reactor) system is presented as a case in point to show its working principle and simulation results are also given to prove its efficiency. The last part of the paper gives some recommendations for future work and improvements.

This work proposes a model based fuzzy controller as a control technique for switch-mode DC/DC converters. These systems have a nonlinear dynamic behavior, as they work in switch-mode. Moreover, they are exposed to significant variations which may take these systems away from nominal conditions, due to changes on the load or on the line voltage at the input. In this paper we analyze the equations of a buck converter and propose a fuzzy gain scheduler among local models based on several operating points. We design a simple state feedback control law for every one of the local models and a fuzzy rule, which acts as a scheduler. The proposed fuzzy control is evaluated by means of computer simulations of these models for reference output, load regulation and line regulation.

In recent years, many real-time applications have emerged on the Internet. Among other types of networks, the Internet also contains a large number of local area networks (LANs) that are based on personal computers and Ethernet. Real-time systems designed for the Internet must consider the impact of this technology. The designers of these systems have a number of computer and network configuration options available and are faced with the problem of choosing the appropriate one. Since it is difficult to find performance results that cover real-time requirements for Ethernet-based personal computer systems, we have developed simple measurement software to obtain performance data. We present the measurements obtained and discuss how the data transmission speed is affected by different components of a distributed system. We show that if the appropriate components are chosen, it is possible to build a distributed system, based on Ethernet and personal computers, that has a high data transmission speed and that can efficiently use Ethernet bandwidth.

In this paper we consider a control scheme for manipulators with elastic joints. The proposed algorithm requires only position signals measurements. This algorithm is an extension of the control algorithm proposed by Loria and Ortega (1995). We have assumed that Loria's and Ortega's model has in addition dynamic friction components on both link and motor sides. We have developed for the proposed model of the manipulator an adaptive version of the control algorithm based on Lyapunov stability theory. In a first part of this paper we present a control algorithm in general. We consider two problems of controlling the position of the end effector of the manipulator and tracking control. Simulation and experimental results are presented. The verification of the new algorithm was investigated a simulation way in MATLAB and SIMULINK and at experimental set-up. An experimental set-up consists of a manipulator with two degrees of freedom, and a control system based on a card with signal processor DS 1102. Simulation and experimental results illustrate properties of the new adaptive control algorithm.

Low frequency harmonics injection into AC power supply and small power factor are the main disadvantages of conventional rectifiers. By using the high power factor correction circuits (HPFCC) the input current has a sinusoidal form and is in phase with the power supply voltage. By solving the problem of power factor with high frequency switching current mode control, another problem arises-that of high frequency harmonics generated in radio-frequency (RF) range by the converter. Therefore the problem of electromagnetic interference (EMI) must be appropriately treated as well. This paper deals with randomized pulse width modulation (RPWM) strategy for the boost rectifier. The randomized modulation principle is introduced in an ordinary PWM control unit which is widely used in unity power factor correction circuits. Introduction of the RPWM results in smaller increases of the total harmonic distortion (THD) in the input current and consequently neglected decreasing of the power factor. On the other hand, this approach causes the high-order harmonics spectral components to be significantly reduced and dispersed around ordinary spectral lines, which means reduced conducted EMI as well.

A special procedure for learning the parameters of Takagi-Sugeno (TS) fuzzy models is proposed in this paper. It is a kind of structured optimization where the antecedent and the consequence parameters are divided into two groups and learned by two separate algorithms. A classical optimization algorithm (random walk with a variable step size) is used for learning the antecedent parameters and a special algorithm for local learning by the least squares method (LSM) is used for identifying the consequence parameters. Two different modifications of this structured optimization scheme are proposed and investigated. Experimentally, it has been shown that the procedure of dividing the whole set of parameters into two subsets being optimized in a multiply loop sequence speeds-up the total learning process. Finally a decomposition principle for reducing the dimensionality of the multi-input fuzzy models is also proposed and investigated on test examples. The proposed methods and algorithms lead to a faster learning and/or faster calculation of the fuzzy models which can be further used for different simulation and control purposes.

The authors propose a robust internal loop compensator and its optimal design method based on H/spl infin/ control. The controller consists of two parts, internal and external loops. The internal loop is used as a compensator for canceling disturbances including difference between reference model and real system, and external loop is designed to meet the performance criterion. The property of the internal loop compensator is compared with that of disturbance observer. Different from the disturbance observer, controller gains and Q filter can be systematically designed, instead of heuristically selected, in the proposed internal loop compensator structure. The proposed controller structure of internal and external loop is characterized by compensator design using reference model, insensitivity of the compensated system to modeling inaccuracies and unknown external disturbances, and satisfaction of desired performance specifications. The performance of proposed controller is demonstrated by experiments of a twin-servo mechanism using two brushless DC linear servo motors.

Optimal control algorithms for closed-loop control of a hybrid stepper motor drive and their microcomputer implementations are discussed. An analytical expression for the average torque of a two-phase hybrid stepper motor with bipolar supply and current controller is developed. Approximate and exact expressions for the optimal control angle of a two-phase hybrid stepper motor with bipolar supply and current controller are derived. An actual hybrid stepper motor drive and the microcontroller-based implementation of the proposed optimal control algorithms are described. The experimental results obtained by positioning of a two-phase hybrid stepper motor drive with phase current controller and incremental encoder suggest that the proposed optimal control algorithms provide maximum acceleration and minimum positioning time of the hybrid stepper motor drive.
