Abstract

The present paper complements the results of several recent papers on higher-order (HO) controllers with automatic-reset. A modification of the two-step tuning of the constrained second-order derivative controllers based on integrator-plus-dead-time (IPDT) models is proposed. In the first step, the linear controller is designed using the multiple real dominant poles (MRDPs) method to avoid the slowdown of the closed-loop dynamics due to the presence of slow poles. In the second step, the smallest time constant of the numerator of the MRDP-optimal controller transfer function is selected as the automatic-reset time constant. The derived control method was tested on a thermal system for the filament disc dryer to demonstrate the deployment, tuning, use and impact of controllers with increasing derivative degree in practical applications. It is shown that the use of HO controllers is similar to the traditional hyper-reset controllers (i.e. series proportional-integral-derivative [PID] controllers) from the user’s point of view. However, the advantages are faster transient responses while maintaining sufficiently smooth input and output shapes of the process with a minimum number of monotonic intervals. The overall design can be seen as a generalisation and discretisation of the Ziegler and Nichols graphical tuning method. One of the main new features is the consideration of a constrained control signal, as is typical for a pulse width modulated (PWM) actuator. Such actuators are often used in speed-controlled electric drives and in power electronics, among other applications.

34. Strategic and Spatial Regulation Tools for Harmonizing Land Use Interests in the Carpathians – Experience from Slovakia

Author

Husar, Milan, Lamy, Sandra, Ondrejicka, Vladimir, and Huba, Mikulas

Abstract

Carpathian ecoregion is one of the last strongholds of biodiversity in Europe. The area spreads across several European countries and contains thriving populations of large carnivores and other species, while staying some of the least-fragmented areas in Europe. At the same time, it is under growing pressure to develop its infrastructure endangering this natural uniqueness. In this paper the pressures to develop the area are described in the light of the existing planning policies in Slovakia. We focus on one of the TransGREEN and ConnectGREEN project cross-border pilot areas located between Czech Republic and Slovakia ‘Beskydy-Kysuce’ where we discuss the pressures to develop the infrastructure and the measures to retain the fragmentation as low as possible. The paper discusses Slovak planning policies on national, regional and local levels. In its second part the focus is on examples of development in this pilot area demonstrating the growing pressure for more infrastructure being built improving the transport connection between Slovakia and Czech Republic. The measures to ease the conflicts between the interests of nature protection and green infrastructure, and the interests of developing the grey infrastructure in this area are presented. Lastly, we review the planning policies and tools in the Slovak national spatial planning system aimed at regulating the development considering all interests in the territory and managing this growth while keeping it in the lines of sustainable development, biodiversity protection and enhancing resilience of this area. The aim is to demonstrate in this pilot area the approach of Slovak planning policies and tools in the Slovak national spatial planning system leading to find the way how to anchor the regulation or adaptive measures so as to create a unified strategic framework for the Carpathian region with a set of recommendations to regulate a massive development in this unique area to avoid the conflicts between green and grey infrastructure.

35. Robust Stability Analysis of Filtered PI and PID Controllers for IPDT Processes.

Abstract

The paper discusses the stability and robustness of the proportional-integral (PI), proportional-integral-derivative (PID), and proportional-integral-derivative-accelerative (PIDA) controller for the integral-plus-dead-time (IPDT) plants. To enable the implementation and measurement of noise attenuation, binomial low-pass filters are added to the traditional design of controllers with ideal transfer functions, and the impact of the low-pass filters on the robust stability of the circuit is studied in detail. The proposed controller tuning, which integrates the suboptimal controller and filter design, is based on explicit tuning formulas derived by using the multiple real dominant pole (MRDP) method. It is shown that by combining derivative actions with possibly higher-order low-pass filters, it is possible to either accelerate the transients or increase the closed loop robustness and that the problem of defining the robust stability area should be addressed at the stage of determining the process model. In addition, if wishing to maintain the closed loop robustness of unfiltered PI control, while increasing the degree of the derivative components, one needs to increase the filtering properties of the low-pass filter used accordingly. Simple analytical relations for setting filtered PI, PID, and PIDA controllers with equivalent robustness are derived. [ABSTRACT FROM AUTHOR]

Abstract

This paper describes a blended learning approach in teaching 'Constrained Time-Delayed Proportional-Integral-Derivative Control.' It is based on the 'learning by doing' paradigm supported by several e-learning tools: by the interactive electronic course materials in Moodle; by the laboratory of low-cost and easy-to-manipulate plants; and by the virtual laboratory WebLAB. These open the access to study and experiment on real systems via Internet for 24 h/day, seven days a week. Synergy of the newly structured theory developed to deal with real-world constraints with the interactive content delivery and with active learning based on simulations, real-time experiments in laboratories, and tele-experiments via Internet offers stimulating and quasi-authentic learning environment. These give students multiple formative feedback, ranging from computer quizzes to plant reactions in a rich variety of authentic situations. Index Terms--Computer-aided instruction, control engineering education, courseware, user-centered design.
