“…Figure shows the final transfer function model developed with the help of the commercial identification tool (here, the Honeywell Profit Suite identification package ). In contrast to the Matlab SIT toolbox, the user is not requested to specify the nominator/denominator orders of the process transfer function.…”

ABSTRACT:The paper demonstrates how a set of pilot plant air blower/heater systems connected to modern industrial distributed control systems (DCS) are used in different control engineering laboratories for the undergraduate level. Student's tasks include the identification of static and dynamic process models and the tuning and commissioning of Proportional-Integral-Derivative (PID) control loops, as well as the utilization of commercial tools for DCS engineering. Using the same pilot plants, DCS and scientific computing environment in different courses lowers the costs, allows the reutilization of results and enables an efficient lab organization. It also supports the process of learning the inner context of different control engineering related subjects. The use of industrial-scale equipment and commercial software helps students to easily integrate in their later teams and to avoid the "reality shock" when making the transition from academia to industry. ß 2015 Wiley Periodicals, Inc.

“…Hence, the user chooses the duration of the experiment. The design of the excitation signal is also crucial for the success of the identification method [5]. For building-use, we assume that the amplitude of the excitation signal should be limited to excite the system around a certain operation point.…”

“…For those controllers a common and effective way is closed-loop tuning based on models gathered by "identification for control", [3], [4]. MacArthur complained in 2007 that there is no simple and robust identification method and that the basic scheme is still trial and error [5]. Far further, a complete procedure for non-adaptive, practical-applicable and as far as possible automated control tuning, that is suitable for all common control loops in buildings, is obviously not adopted nor available to practitioners and the industry.…”

Within custom-made energy or HVAC systems, control quality of the widespread PI and PID controllers is in general poor due to high tuning costs for each controller and almost unique specifications of each controlled system. We propose a control tuning method, which needs as little as possible a priori knowledge, which runs as far as possible automated, and which is applicable for all state-of-the-art building automation systems. The method is non-adaptive and suitable for initial set up as well as retuning purposes. We demonstrate the method within a multifunctional office building with a complex energy system, where the method's application led to high control quality improvements.

“…The motivation for closedloop testing is to reduce implementation time and/or effort of the initial implementation as well as the ongoing need to re-identify the model of an industrial application in light of processes changes. These closed-loop testing methods, which require a preliminary or existing model, utilize uncorrelated dither signals either introduced as biases to the controller MVs or injected through the steady-state LP or QP, where additional logic or optimization of the test protocol may be performed (Kalafatis et al 2006;MacArthur and Zhan 2007;Zhu et al 2012). …”

Model predictive control (MPC) has become the standard for implementing constrained, multivariable control of industrial continuous processes. These are processes which are designed to operate around nominal steady-state values, which include many of the important processes found in the refining and chemical industries. The following provides an overview of MPC, including its history, major technical developments, and how MPC is applied today in practice. Possible future developments are provided.
