The increasing size of modern buildings and building complexes, and the difficulty of obtaining competent operating personnel have led to an increasing use of central supervisory control systems. These systems allow one person, at a central location, to monitor and control the operation of up to several thousand elements of the heating, ventilating and

Control situations in supervisory control
Cognition, Technology & Work, 2004It is widely acknowledged that the safe and efficient supervisory control of complex dynamic systems requires that human operators are capable of checking the state of the controlled system against given performance criteria. In addition, it is important to consider how changes in the state of the controlled system and its environment influence the ...

Supervisory Control with Partial Observations
2013In discrete-event systems it is often not realistic to assume that all events of such a system are observable. This is either because some events are typically not directly observable from their very nature (such as failure events, internal hidden events, etc.) or it is too costly to have sensors and observe every event that can occur in the system ...

Supervisory control and remote metering
Electrical Engineering, 1936Supervisory control and remote metering installations on the electrified section of the Pennsylvania Railroad are outlined herein. A brief history of the growth of electrification on this railroad, and of the supervisory control and remote metering installations which accompanied the electrification is given, together with the locations at which the ...

Supervisory Control and Optimization
2010In the first part of this chapter, structures and algorithms of Model-based Predictive Control (MPC) and on-line process set-point optimization are presented, corresponding to implementations in the DiaSter system. The principle of MPC is first recalled, as a special case of the general principle of ”open loop with feedback optimal control”.MPC is now ...

This paper discusses how the adaptive control paradigm can be used for reducing the computational complexity of the synthesis of supervisory controllers for discrete event systems (timed or untimed) with partial observations. The adaptive control paradigm simplifies the design by assuming a priori that the control design is decomposed in two parts. The

Route-Based Supervisory Controls
2018This chapter covers steps to design a real-time Route-based EMS for a power-split PHEV. The EMS controller adjusts power distribution between two energy sources, the engine and the battery. A schematic of the Route-based EMS is shown in Fig. 8.1. Trip Planning module employs the simple powertrain model and predicted speed trajectory to find optimum ...
