This paper presents the simulation and method of using the robust control theory (decentralized and centralized control systems) for temperature control of superheated steam in the once-through boiler. As the theoretical base, we used synthesis of robust H∞ controllers that minimize the standard mixed sensitivity function. For the decentralized temperature control, we applied the classical cascade structure where we used the P controller in the secondary loop and the robust controller in the primary loop. Besides this arrangement, we used a single robust controller in the feedback loop. The centralized robust control structure was chosen as the third option. Results of the simulation and the good robust qualities of the robust controller presented in this paper confirm that the controller can provide a basis for industrial implementation of sophisticated algorithms which are prepared.

The main topic of this article was to evaluate control structure with reference model for control of electric drive. The well known cascade control structure is used in industrial electric drives control units, where current, speed and position loops are encapsulated together. The control theory knows the advanced control structures where reference model and real plant behavior is compared to obtain error signals to calculate proper control action. The implementation difficulties are the main disadvantage if we want to evaluate the properties and limitations of this nontraditional control structures.

Small and Medium Enterprises (SMEs) are a crucial part of European economy, in fact, 99% of the manufacturing business in Europe are SMEs, which makes European economic performance directly linked to the performance of its SMEs. Key performance indicators (KPIs) are crucial in today's management of SMEs. In this paper, we analyze a proposed model from the Future SME project of the 7th Framework Programme to drive KPIs on SMEs. We study the model applied on an assembly line and propose improvements to the model, as well as recommend future areas of development for such model aiming to improve the control over the KPIs.

The presented paper deals with measurements and modeling friction process in linear pneumatic actuators. There are described two friction models. The first model is static, the second is dynamic. In particular, it is a Striebeck and Lund-Grenoble model. The used method of measurement of friction on real pneumatic drive DGPL 25-900-PPV-A-KF-B is described together with chosen results of measurements. For example, it is dependency of friction force on velocity, dependency of deflection of carriage of pneumatic drive on load. The comparison of mathematical model with real system is presented at the final part of the paper.

The paper deals with an automatic tuning of input shaping filter added to the classic cascade control of the two-mass flexible system driven by an electric servomotor. The considered input shaping filter has a structure of weighted sum of four time delays. The tuning algorithm contains two steps. The first step of this method is to roughly estimate the damped frequency of the system. In the second step more precise estimations of the damped frequency and damping factor are provided. The function of the autotuner is demonstrated on the linear model of a cable robot with flexible rope.
