The tandem cold rolling of metal strip is a large, highly complex nonlinear multivariable process the control of which poses a significant engineering challenge. Existing controllers have proven to be susceptible to disturbances and uncertainties in process variables and attempts to increase robustness to these phenomena have had their own drawbacks so a new approach is needed.

Tandem Cold Metal Rolling Mill Control deals primarily with a novel and practical advanced method for control of tandem cold metal rolling processes based on the recently emerging state-dependent Riccati equation technique. Background material is presented to assist the reader with a general control background to appreciate the significance and practical advantages of the new advanced control scheme over conventional and more recently proposed advanced techniques. A short history of tandem cold rolling is followed by descriptions of various types of cold rolling processes and a basic mathematical model of the process. The diverse conventional and advanced control methods and their advantages and disadvantages are compared, and a detailed treatment of the theoretical and practical aspects of the state-dependent algebraic Riccati equation technique given. The specific details of the new procedure are described in a manner not requiring detailed expertise in the control of tandem cold rolling. The results of simulations performed to verify the control model and overall system performance with the new controller coupled to the process model are included. Simulation results and data derived from actual operating mills are compared so as to make concrete the improvements in performance using the new method. Additionally, material is included which shows the new technique to be capable of extension to the control of a broad range of large-scale complex nonlinear processes.

Engineers working with control systems in the metal processing industries will find that the advanced control ideas promulgated here will be of considerable benefit in increasing the robustness of their systems and, therefore, the consistency of their products. Tandem Cold Metal Rolling Mill Control will also interest academics and graduate students interested in advanced automatic control and its practical application and in the uses of the state-dependent Ricatti equation in particular.

Stylist of the stars and successful fashion designer, Leila Darkchylde, is on top of the world - in her professional life that is. Her love life sucks. She expected to spend another Singles Awareness Day, er, Valentine's Day alone when she receives an unexpected package. When Leila opens the giant cardboard box it is to find none other than the masochistic, bass guitarist Morg Di Morte, of the heavy metal band The Necromancers. Morg is naked and tied up with red ribbon like some kind of present. This is only the first of many strange surprises in store for Leila this crazy, topsy-turvy Valentine's Day! This is the illustrated version which contains ink drawings done by author KuroKoneko Kamen.


Process Control For Sheet-metal Stamping

Process Control for Sheet-Metal Stamping is a comprehensive and structured approach to the design and implementation of controllers for the sheet metal stamping process. The use of process control for sheet-metal stamping greatly reduces defects in deep-drawn parts and can also yield large material savings from reduced scrap. Sheet-metal forming is a complex process and most often characterized by partial differential equations that are numerically solved using finite-element techniques. In this book, twenty years of academic research are reviewed and the resulting technology transitioned to the industrial environment. The sheet-metal stamping process is modeled in a manner suitable for multiple-input multiple-output control system design, with commercially available sensors and actuators. These models are then used to design adaptive controllers and real-time controller implementation is discussed. Finally, experimental results from actual shopfloor deployment are presented along with ideas for further improvement of the technology. Process Control for Sheet-Metal Stamping allows the reader to design and implement process controllers in a typical manufacturing environment by retrofitting standard hydraulic or mechanical stamping presses and as such will be of interest to practising control engineers working in metal-working, automotive and aeronautical industries. Academic researchers studying improvements in process control and how these affect the industries in which they are applied will also find the text of value.
