Tato práce se zabývá řízením dynamických systémů v reálném čase a navazuje na předchozí bakalářskou práci. V její úvodní části jsou definovány základní pojmy z oblasti řízení a regulace, aby byl čtenář uveden do problematiky. Systémy v rámci této práce jsou popsány pomocí diferenciálních rovnic, proto je část práce věnována seznámení se s různými metodami řešení diferenciálních rovnic a jejich přesnosti. Je také představena Moderní metoda Taylorovy řady, kterou řeší diferenciální rovnice přiložené programy. Pro simulaci byl inovován existující návrhový systém a implementováno několik dalších pomocných a výukových nástrojů. Je zmíněno i řešení dopravního zpoždění.

This article presents the development and application of a real-time production control system, integrating hardware and software for continuous monitoring of industrial operations and costs. The proposal aims to promote greater operational efficiency and agility in decision-making. The main objective is to present a proposal for applying the concept of paperless manufacturing, here referred to as “right time,” in a production line of medical and hospital products, in order to identify and quantify the benefits generated by the proposed environment. The adopted methodology was action research, encompassing the system design, its technological architecture, and its application in a simulated manufacturing environment. The results demonstrate significant gains in operational visibility, waste reduction, and improvement in cost control. With the implementation of the developed improvement proposal, a reduction of 32% in document-filling time on the assembly line is estimated, in addition to a 5% decrease in annual paper consumption. Other observed benefits include improvements in internal communication, document control, workplace organization, and the execution of routine activities. Additionally, the study contributes to digital transformation in industry, aligning with the principles of Industry 4.0 and reinforcing the importance of digitalization as a strategic tool for the modernization of production processes.

This system provides low power consuming and low cost wireless sensor network. This system provides a real time temperature and humidity. It also gives proportional control action. This system consists of TI’s MSP430 microcontroller which consumes ultra low power and improves the overall system performance. The Sensorion’s SHT 11 sensor is used to measure temperature and humidity. Sensor SHT 11 consumes low power and gives the fully calibrated digital output. Zigbee technology is used for wireless communication. Zigbee is low power consuming transceiver module. It operates within the ISM 2.4 GHz frequency band. AT and API command modes configure module parameters. RF data rate is 250 kbps. To achieve the proportional control triac and MOC 3022 are used. The star network topology is implemented. The temperature of earth goes on increasing due to global warming, deforestation, pollution, etc. Due to this the temperature of atmosphere also increases which is harmful and dangerous for many systems. This system provides precise control of temperature and humidity in Green House, Art Galleries and Industries.

This thesis is done as a complementary part for the active magnet bearing (AMB) control software development project in Lappeenranta University of Technology. The main focus of the thesis is to examine an idea of a real-time operating system (RTOS) framework that operates in a dedicated digital signal processor (DSP) environment. General use real-time operating systems do not necessarily provide sufficient platform for periodic control algorithm utilisation. In addition, application program interfaces found in real-time operating systems are commonly non-existent or provided as chip-support libraries, thus hindering platform independent software development. Hence, two divergent real-time operating systems and additional periodic extension software with the framework design are examined to find solutions for the research problems. The research is discharged by; tracing the selected real-time operating system, formulating requirements for the system, and designing the real-time operating system framework (OSFW). The OSFW is formed by programming the framework and conjoining the outcome with the RTOS and the periodic extension. The system is tested and functionality of the software is evaluated in theoretical context of the Rate Monotonic Scheduling (RMS) theory. The performance of the OSFW and substance of the approach are discussed in contrast to the research theme. The findings of the thesis demonstrates that the forged real-time operating system framework is a viable groundwork solution for periodic control applications.

The National Bureau of Standards, Industrial Systems Division designed the Real-time Control System where high-level goals are decomposed through a succession of levels, each producing strings of simpler commands to the next lower level. The bottom level generates the drive signals to the robot, gripper, and other actuators. Each control level is a separate process with a limited scope of responsibility, independent of the details at other levels, thus providing a foundation for future modular, "plug compatible" hardware and software for robots and real-time sensory interactive control applications.

To improve the stability and accuracy of motor control system for beamlines, the beamlines with motor adjustment mechanism collocate with the real-time firmware motor control system through the high-definition motor mechanism. Because the real-time motor control system does not need to be connected with the computer for a long time, it improves the speed, stability and accuracy of closed loop operation and thus promotes the controlling ability of motor. As a result, the real-time motor control system will improve the stability and accuracy of the entire motor control system with beamlines.

The article elaborates the design and construction of automatic light control system. The developed electronic system eliminates the disadvantages of the existing systems by taking date and time from the GPS, as it also gives information about the position of the system. Based on the results the microcontroller calculates and automatically detects geographical area and retrieve relevant data for sunrise and sunset in the area, respectively ensures very precise ON/OFF mode of the lighting system. It doesn't need operator maintenance and initial installation setup. The developed electronic device increases bulb life in result of the dimming effect. On the other hand this decrease of the illumination leads to reduce in the energy consumption.

This report describes the development of a microprocessor based hardware design that automates Intelligent Transportation Systems (ITS) network configuration for differing modes of traffic controller operation. The design, called Controller Interconnection Network (CIN), is scalable. Up to 20 traffic controllers can be interconnected with a single network or in up to four parallel networks, permitting multimodal operation. The CIN enables communication between controllers and also allows users an interface to enter controller settings. The design allows remote control of some operations via a web-based interface.
