### The Mechatronic Approach To The Optimal Control Of The VSCF GENSET

**Vladimír ŘEŘUCHA, Zdeněk KRUPKA, Jan LEUCHTER**

#### Abstract

The new generation of electrical power generating sets (GS) is based on some new technologies. Constant speed sets with combustion engines driving brushless field excited synchronous generators are replaced by optimally controlled variable speed diesel engine, driving robust permanent magnet generator (SGPM) equipped with power electronics frequency and voltage control (VSCF technology). The new 3rd GS generation (GS3G) represents the sophisticated mechatronic system, consisting of mechanical parts, electromechanical energy conversion part, power electronic converters for electrical energy transformation and optimal control feedback system. Mechatronic approach to the theoretical analysis and synthesis, development and implementation, using modern methods of mathematical modeling and simulation and optimal control procedures, gives the chance to solve the GS3G problem successfully.

### Object oriented design for random number generators

**Alexandr Štefek**

#### Abstract

This paper shows basic principles for object oriented design (OOD) in random number generators development. With OOD we can define basic class with virtual (and abstract) functions. Then its possible, in inherited classes, override base method implementation.

### Parallel async execution - message based

**Alexandr Štefek**

#### Abstract

This paper present implementation of parallel execution. If we use parallel proces in programs we have to solve synchronization. We show the effective implementation of parallel execution without using critical sections, semaphores, mutexes or events.
