This paper gives a framework of supervisory control of boiler drum level system. The design and implementation of this process is done by the LabVIEW software. The data of the process variables Level from the boiler system need to be logged in a database for further analysis and supervisory control. A LabVIEW based data logging and supervisory control program simulates the process and the gener...

Fuzzy controller is one of the succeed controller used in the process control in case of model uncertainties. But it my be difficult to fuzzy controller to articulate the accumulated knowledge to encompass all circumstance. Hence, it is essential to provide a tuning capability. There are many parameters in fuzzy controller can be adapted, scale factor tuning of normalized fuzzy controller is on...

This paper discusses problems related to partial observation supervisory controllers with possibly faulty sensors in the framework of discrete-event systems. At initialization all controller sensors are operational such that all sensors correctly communicate their event observations to the controller. Sensor failures are unobservable. After a sensor fails, it sends no signals to the controller....

In this paper, we integrate nonlinear control and supervisory control theory to design a controller of a heating, ventilating and air conditioning (HVAC) system. First we design the nonlinear controllers by Lyapunov theory and backstepping. Then we create the discrete abstraction of this system and thus derive the discrete event system model from the continuous plant. Finally we design the supe...

This paper proposes a supervisory control structure for networked systems with time-varying delays. The control structure, in which a supervisor triggers the most appropriate controller from a multi-controller unit, aims at improving the closed-loop performance relative to what can be obtained using a single robust controller. Our analysis considers average dwell-time switching and is based on ...

Progress in aircraft designs heavily depend on Automatic Flight Control System (AFCS). In this work a fuzzy sliding mode controller is designed as a supervisory controller in aircraft pitch control systems and different control strategies to model a pitch controller based on design a pitch angle control in autopilot are invistigated. A performance evaluation based on time response specification...

Abstract The operation of future wind power plants (WPPs) will rely on maximizing overall profit rather than production. Factors like current electricity price, grid code compliance, and maintenance costs affect operational decision. Therefore, it is expected that plant control strategies trade different objectives while respecting the industrial practice, where levels in hierarchy may be provi...

A key challenge in the synthesis and subsequent analysis of supervisory controllers is impact state-space explosion caused by concurrency. The main bottleneck often memory needed to store composition plant requirement automata resulting supervisor. Partial-order reduction (POR) a well-established technique that alleviates this issue field model checking. It does so exploiting redundancy with re...

A supervisory scheme is proposed that implements Stepwise Safe Switching Logic. The functionality of the supervisory scheme is organized in the following eight functional units: StepWise Safe Switching unit, Common controllers design unit, Experimentation unit, Simulation unit, Identification unit, Trajectory cruise unit, Operating points unit and Expert system unit. The supervisory scheme orch...

An essential issue in the formation control of Unmanned Aerial Vehicles (UAVs) is to design a reliable controller in their path planner level to handle all interactions between the continuous dynamics of the system and inherent discrete nature of the decision making unit, which has been embedded to coordinate the control submodules. In this paper, we have proposed a new approach of hybrid super...
