Abstract: The author discusses the use of an educational popular continuous simulation language for designing a digital control system. The TUTSIM dynamic simulation program is capable of simulating control systems with a digital controller in the loop. A built-in parameter estimation routine is employed to achieve control parameter optimization. PID control of a first order system with time delay is presented as an illustration of the technique. However, because the optimization is based on simulation of the system at various points in the control parameter space, the method is applicable to nonlinear systems and more complex digital control algorithms. Furthermore, the system error used and the performance index based on the error are easily changed

Abstract: Computer-Assisted Simulation of Dynamic Systems with Block Diagram Languages explores the diverse applications of these indispensable simulation tools. The first book of its kind, it bridges the gap between block diagram languages and traditional simulation practice by linking the art of analog/hybrid computation with modern pc-based technology. Direct analogies are explored as a means of promoting interdisciplinary problem solving. The reader progresses step-by-step through the creative modeling and simulation of dynamic systems from disciplines as diverse from each other as biology, electronics, physics, and mathematics. The book guides the reader to the dynamic simulation of chaos, conformal mapping, VTOL aircraft, and other highly specialized topics. Alternate methods of simulating a single device to emphasize the dynamic rather than schematic features of a system are provided. Nearly-forgotten computational techniques like that of integrating with respect to a variable other than time are revived and applied to simulation and signal processing. Actual working models are found throughout this eminently readable book, along with a complete international bibliography for individuals researching subjects in dynamic systems. This is an excellent primary text for undergraduate and graduate courses in computer simulation or an adjunct text for a dynamic systems course. It is also recommended as a professional reference book.
Karayanakis, Nicholas "Advanced System Modelling and Simulation With Block Diagram Languages" CRC Press 1995 view details
Abstract: This work was conceived as a logical sequel to Computer-Assisted Simulation of Dynamic Systems with Block Diagram Languages published by CRC Press in 1993. Its contents reflect suggestions, challenges and requests from academic, industrial, and military people in the U.S. and from around the world. The main objective of this book is two-fold: first to discuss the role of block languages as tools and to expose the technical features of several advanced languages. In the interest of diversity, we have selected ACSL/GM (Advanced Continuous Simulation Language/Graphic Modeller), ESL (European Space Agency Simulation Language), Extend, MATRIX(subscript x), SIMULINK, SystemView, TUTSIM (Twente University of Technology Simulation Language, U.S. version), and VisSim. Most of the time, languages are discussed alphabetically. These discussions revolve about the technical aspects of each language. There is no intent of product comparison - that is a reader's task. Secondly, we have included discussions on critical simulation-related topics and on material pertaining to special simulation demands and their solutions. Our efforts toward the synthesis of an informative and self-contained book on block languages led to the inclusion of a review section on block diagram algebra and applied transfer functions. To reiterate a position of long standing, we believe that block diagram algebra is clearly a branch of mathematics and is necessary knowledge for those working in continuous dynamic system simulation.

Tutsim is a 'hands-on' interactive simulation program for dynamic systems. The program is suitable for processes that can be described as a number of connected black boxes. The program can be used for continuous, semi-continuous, batch, dynamic and static processes.
Tutsim is no longer marketed. 20-sim has been developed at the Control Laboratory of the University of Twente as successor of the famous TUTSIM package.
