In this paper LQG controller for TRMS without and with sensor, actuator failure is designed. Implementation of LQG controller for TRMS is done under no failure of sensor, actuator. TRMS output with LQG controller and reliable H infinity controller are compared without and with sensor, actuator failure. The objective of the proposed technique is to prove the H infinity controller is reliable ove...

Today, robots and unmanned aerial vehicles are being used extensively in modern societies. Due to a wide range of applications, it has attracted much attention among scientists over the past decades. This paper deals with the problem of the stability of a four-rotor flying robot called quadrotor, which is an under-actuated system, in the presence of operator or sensor failures. The dynamica...

Sensor application requirements vary tremendously, ranging from densely deployed habitat-monitoring setup to the real-time constrained military applications. This paper presents the design of a novel self-organizing framework for SANETs (Sensor and Actuator Networks). We assume two wireless interfaces at the actuator nodes, one to communicate with sensor nodes, and the other, for the neighborin...

We study the coordination and control problem of distributed discrete-event systems with synchronous communication, in the presence of subsystems whose sensors and/or actuators may be affected by unexpected failures. We model sensor failures as permanent loss of observability of certain sensor events that belong to a subsystem, while characterize actuator failures as loss of controllability of ...

Controllers capable to perform failure diagnosis have an additional diagnostic output to detect and isolate sensor and actuator faults. A linear such controller is usually called a four-parameter controller. Neural networks have proved to be a very powerful tool in the control systems area, where they have been used in the modelling and control of dynamical systems. In this paper, a neural netw...
