Classroom lectures will consist of theoretical explanations of the fundamental aspects of each lesson, as well as solutions to questions raised by the students based on their own self-study. There will be two kinds of laboratory sessions: simulation on a software package specialized on dynamical systems and control and real-time control of industrial devices, where the students will test the validity of the theoretical apparatus of the course.
Module I: Discrete, sampled and hybrid systems In this module, the simple digital control loop is presented and the effect of the introduction of the computer in such loop is studied. A/D and D/A converters are introduced and the main advantages and disadvantages of digital control systems are analyzed in comparison to the analog control ones. The different types of systems appearing in the digital control loop are presented and the necessary tools are introduced for their study (Z transform, Modified Z Transform, ...) Module II: Analysis The techniques needed to study the stability and behavior of discrete systems in the temporal and frequency domains are introduced. The behavior of discrete and sampled systems is characterized, and it is shown how to obtain a discrete model that verifies a set of specifications. The effect of sampling from the frequency point of view is analyzed, as well as the effect of the sampling and retention process on a signal by means of a Zero Order Hold. Module III. Design and synthesis of controllers Digital controller design techniques are introduced, both by emulation of analog controllers and by direct digital design. Various techniques for controller synthesis are presented, such as the Truxal method and pole placement. They are generalized for the case of two-degree-of-freedom control systems, so that systems can be obtained that meet both reference tracking and disturbance rejection specifications.

Feedback control systems are distinguished from feedforward systems in that they have no reference sensor to give timeadvanced information about the disturbance being controlled. They are used in a variety of applications for the active control of sound and vibration, particularly where the primary sources that generate the disturbance cannot be directly observed, or in which there are too many primary sources to economically obtain reference signals from each one. The most important example of an active feedback sound control system is in active headsets.
The area around the stadium should provide easy access for emergency vehicles (preferably unimpeded and continuous access). In particular, easy access is required to fire mains/hydrants and the area where the main fire alarm control panel is located. The locations of firefighting facilities should be well known to the firefighting service in advance of a call-out. This will require coordination between the stadium management team and the relevant emergency services. Firefighting equipment should also be well documented/signposted on-site, and access should be maintained at all times. Firefighting equipment should be inspected and maintained at regular intervals. A detailed maintenance plan should be used to ensure that the systems, staff and equipment remain fully operational (see Section 4.4 for procedures and policies).
Closed-circuit television (CCTV): adequate CCTV systems with sufficient monitor screens and camera controls should be located in the VOC to undertake surveillance monitoring of the stadium and its immediate vicinity. 041b061a72
