The task of implementing supervisory controllers is non-trivial, even though there are different theories that allow automatic synthesis of such controllers in the form of automata. One of the reasons for this discord, is the asynchronous interaction between a plant and its controller in implementations, whereas the existing supervisory control theories assume synchronous interaction. As a cons...

In this article, our aim is to perform security threat assessment of networked control systems (NCS) systems with regulatory and supervisory control layers. We analyze the performance of a proportional-integral controller (regulatory layer), and a model-based diagnostic scheme (supervisory layer) under a class of deception attacks. We adopt a conservative approach by assuming that the attacker ...

An adaptive control scheme for mechanical manipulators proposed. The control loop consists of a network for learning the robot’s inverse dynamics and on-line generating the control signal. Some simulation results were provided to evaluate the design. A supervisor was used to improve the performances of the system during the adaptation transients. The supervisor exerts two supervisory actions. T...

The Supervisory Control and Data Acquisition (SCADA) systems are gathering information or data from different sensors nodes sent in remote areas and after that transmitted to a focal controller which then oversees and controls this information. Wireless communications for Supervisory Control and Data Acquisition (SCADA) is obliged to applications where wired correspondences to the remote site a...

It is difficult to achieve excellent tracking performance for a two-joint leg rehabilitation machine driven by pneumatic artificial muscles (PAMs) because the system has a coupling effect, highly nonlinear and time-varying behavior associated with gas compression, and the nonlinear elasticity of bladder containers. This paper therefore proposes a T-S fuzzy theory with supervisory control in ord...
