Improving System Availability using Overlapping Decomposition-Based Robust Control

This paper proposes a subsystem-based robust control approach using overlapping decomposition to improve system availability by effectively handling fault information. The stability of the system is proven using Lyapunov stability criteria, and performance evaluation is conducted on an interconnected continuous-time stirred tank reactor (CSTR) with recycle. The proposed scheme effectively controls faults to avoid costly failures.

  2. Abstract High availability is always expected for the continuation of operations in a plant. However, this objective is unable to attain due to unplanned breakdowns. This paper works on improving the availability of system by accurately handling the fault information. This was made possible by proposing a subsystem-based robust control. The overlapping decomposition was employed to tackle the variations independently for each state. The stability of the system was proved further using Lyapunovstability criteria. Performance evaluation was then conducted on an interconnected continuous time stirred tank reactor (CSTR) with recycle. The proposed scheme effectively controlled the faults to avoid costly failures.

  4. Water Leakage in Jeddah City • In Jeddah city, there is a huge problem of water leakage [1]. According to an estimate, if 100 liters of water is supplied to the consumers, only 40 liters is being used, and 60 liters is lost due to leakage problems in their water pipeline network system.
