Linear combustion engine

This contribution describes new types of the combustion engine, called as Linear Combustion Engine (LCE). The main features of this new engine are: Nonexistence of any shaft, flywheel or other rotation components. The output of this engine is not mechanical torque and power on the output shaft, but direct electric power on the linear motor-generator. This linear generator translates the mechanical periodic moving of the piston rod to electric energy as the output of this engine. The linear combustion engine is an electromechanical converter the chemical energy of hydrocarbon or hydrogen fuel as an input to electric energy as an output. Another solution of this problem is presented by an electrochemical converter well known as fuel cells for direct chemical energy changing to electric energy. Comparison of these both possibilities shows, that the linear combustion engine brings some advantages. The main advantage of LCE is higher power density and less production cost in comparison with fuel cells. These properties define such application areas as power source for serial hybrid vehicles, mobile UPS and light mobile electric source for military information systems. To achieve a good function, high reliability and low exhaust pollution of this system it is necessary to design a very sophistical powerful control system.

IFAC - work in technical Committee on "Transportation System and Vehicles "

The project provides a financial support enabling the cooperation with the Transportation Systems and Vehicles Technical Committee of International Federation of Automatic Control (IFAC). As a member of the IFAC Technical Committee, the recipient is responsible for the planning and monitoring of technical events, such as symposia, conferences and workshops, with the NMOs acting as hosts. They also promote their respective areas in other ways, such as establishing contacts with other international organizations, publishing reports on selected topics, etc. The IFAC Transportation Systems and VehiclesTC covers specialized topics in control engineering. Its tasks among many others include promoting interest in emerging control subfields, assuming responsibility for technical meetings (or for series of such), providing for cooperation among specialists of their particular field, etc.

Redundant Drives and Measurement for Hybride Machine Tools

In previous GACR project there has been developed the principle of redundant actuation for new concepts of hybride machine tools with improved properties. Further there has been develop the way of control of redundant drives. This principle, control and accessible improved properties have been verified on laboratory models.The objective of this project is to verify these items on realistic prototype of machine tool togehther with development of control for simultaneous measurement of position of drives as well as directly of platform with tool. The project goals are 1. To design of hybride machine tool with redundant drives and to manufacture its functional prototype with realistic properties. 2. To implement the control of redundant drives and to verify its function on realistic prototype of machine tool. 3. To design laser tracker for measurement of platform position and to manufacture its functional prototype. To analyze the accessible measurement accuracy. 4. To develop the control of redundant drives with measurement of more position variables.

Modernization of education's approach in the courses "Electronic systems design".

The main project target is full modernization of education's approach in the courses "Electronic systems I and II" and in advances courses " Electronic systems design". New education concept requires using of the new generation of powerful CAD systems for electronic design. As example of these modern systems is the design system OrCad release 9.2 . This system is main tool for our modernization ideas. Buying of these systems and its composition on our education systems is main task of this project.

Control of Redundant Parallel Robots

Kinematics synthesis one or several variant of space parallel robot with target maximize working space, minimize number of singular points and full utilization parallel robots properties. Research of optimal control of redundant parallel robots based on cooperation drive for improving robot's dynamic properties. Second solution is tagonistic utilization of drive for improving robot's inelasticity. Next target is laboratory verification one of designed control's algorithms. Mechanical and electronical design of laboratory modelone of variant space robot is final step of this research.
