This paper deals with optimal operation of a three-product Dividing-Wall Column (DWC). The main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. Exact local method is used to find the best controlled variables as single measurement or combination of measurements ...

We propose a safety-optimizing method for safety strategies of human-care robots using our danger evaluation method. First, various safety evaluation methods are discussed, and an optimizing method of safety design is proposed. Second, we make a comparative study of two general safety control methods, and then a method of optimizing robot control is proposed. These proposed methods enable us to...

Self-optimizing systems are technical systems with the ability to learn, communicate with each other, and optimize their behaviour autonomously in response to environmental changes. The operation of such systems requires close interaction between mechanics, electronics, control engineering and software engineering. This paper addresses the conceptual design of controllers based on the principle...

Self-optimizing control provides nearly optimal operation of process systems in face of varying disturbances, where the inputs are adjusted to hold selected controlled variables (c) at constant setpoints. It is possible to have better self-optimizing properties by controlling linear combinations of measurements (c = Hy) than by controlling individual measurements. Previous work focussed on sele...

nowadays the researches have indicated the fact that using synthetic antioxidants as food additives in edible oils can have adverse effects on human health. so preparing antioxidation resources for reduction of oxidation stress effects is important. the aim of this project was, representing a natural antioxidant source with frap test. the present study optimized the ultrasound assisted extracti...
