The extensively revised second edition expands and refines on important work in the ubiquitous PID form of control with material covering:
Autotuning of PID Controllers is more than just a monograph, it is an independent learning tool applicable to the work of academic control engineers and of their counterparts in industry looking for more effective process control and automation.
Comments on the first edition:
This book is written in a way which not only makes it easy to understand but is also useful to those interested in or working with PID controllers.
The book will be useful to manufacturers and users of control equipment, and also to researchers in the field of automatic tuning.
How should I carry out the identification of my process in order to obtain a good model?
How can I assess the quality of a model with a view to using it in control design?
How can I ensure that a controller will stabilise a real process sufficiently well before implementation?
What is the most efficient method of order reduction to facilitate the implementation of high-order controllers?
Different tools, namely system identification, model/controller validation and order reduction are studied in a framework with a common basis: closed-loop identification with a controller that is close to optimal will deliver models with bias and variance errors ideally tuned for control design. As a result, rules are derived, applying to all the methods, that provide the practitioner with a clear way forward despite the apparently unconnected nature of the modelling tools. Detailed worked examples, representative of various industrial applications, are given: control of a mechanically flexible structure; a chemical process; and a nuclear power plant.
Process Modelling for Control uses mathematics of an intermediate level convenient to researchers with an interest in real applications and to practising control engineers interested in control theory. It will enable working control engineers to improve their methods and will provide academics and graduate students with an all-round view of recent results in modelling for control.
Practical PID Control covers important issues that arise when a PID controller is to be applied in practical cases. Its focus is on those functionalities that can provide significant improvements in performance in combination with a sound tuning of parameters. In particular, the choice of filter to make the controller proper, the use of a feedforward action and the selection of an anti-windup strategy are addressed. Further, the choice of the identification algorithm and of the model reduction technique are analysed in the context of model-based PID control. Widely adopted PID-based control architectures (ratio and cascade control) and performance assessment are also covered. For these topics, recent contributions are explained and compared with more standard approaches. A large number of simulation and experimental results are provided in order better to illustrate the different methodologies and to discuss their pros and cons. Practical PID Control is a helpful and instructive reference for researchers, graduate students and practitioners in process control.
The presentation is completed by a number of appendices containing technical background associated with the main text including a manual for the ADEX COP platform developed by the first author to exploit the capabilities of adaptive predictive control in real plants.
ADEX Optimized Adaptive Control Systems provides practicing process control engineers with a multivariable optimal control solution which is adaptive and resistant to perturbation and the effects of noise. Its pedagogical features also facilitate its use as a teaching tool for formal university and Internet-based open-education-type graduate courses in practical optimal adaptive control and for self-study.
Control of Integral Processes with Dead Time provides a unified and coherent review of the various approaches devised for the control of integral processes, addressing the problem from different standpoints. In particular, the book treats the following topics:
• how to tune a PID controller and assess its performance;
• how to design a two-degree-of-freedom control scheme in order to deal with both the set-point following and load disturbance rejection tasks;
• how to modify the basic Smith predictor control scheme in order to cope with the presence of an integrator in the process; and
• how to address the presence of large process dead times.
The methods are presented sequentially, highlighting the evolution of their rationale and implementation and thus clearly characterising them from both academic and industrial perspectives. Control of Integral Processes with Dead Time will serve academic researchers in systems with dead time both as a reference and stimulus for new ideas for further work and will help industry-based control and process engineers to solve their control problems using the most suitable technique and achieving the best cost:benefit ratio.
