An algorithm for calculating the reference temperature in the rooms of a building was developed. The algorithm properly reduces the reference temperature in the rooms when they are not occupied, and at the appropriate start time recover the reference temperature back to the defined value. Simulations show that in the rooms where the occupancy is known in advance, the desired level of guest comfort can be preserved with the proposed algorithm with an approximately 10 % lower energy consumption for heating and cooling of the rooms than with the constant reference recovery time setting.

A domain specific modeling language (DSL) ProcGraph is presented together with its corresponding code generation tool that was designed for the development of software in the domain of procedural process control systems. The advantage of using a domain specific language is that not only the programmers, but also domain experts are able to understand and modify the code.

The paper presents model identification issues of the self-tuning nonlinear controller ASPECT, intended for the advanced control of nonlinear processes but implemented on an industrial PLC platform. A special batch-wise algorithm that is based on the Takagi–Sugeno model and uses "fuzzy instrumental variables" technique is described in the paper. Many robustness problems of the classical adaptive approaches can be circumvented by the proposed batch-wise approach combined with a supervisory mechanism. The paper includes experimental results on a hydraulic pilot plant and simulation case studies.

An original Monte Carlo approach has been proposed for investigation of the influence of variable skin parameters on the evolution of skin burn injuries. The data from the sensors mounted on the mannequin is used in a thermal model of the skin, the result of which is an estimate of the degree of injury that would occur to a human exposed to the same flame conditions. Analysis of predicted skin injury level shows how the process of skin burn evolution depends on the skin properties.

This article proposes a closed-loop control structure utilising production performance indicators (pPIs) to simplify plant-wide control. pPIs represent the translation of operating objectives. The idea was implemented on the procedural model of a production process for a polymerisation plant, and two types of controllers were tested: a controller based on look-up tables and an advanced model predictive controller (MPC).
