Adaptive Gravitational Search Algorithm-based Compensator for Control Valve Stiction

Control loop performance monitoring and improvement techniques are becoming essential to chemical industries due to the substantial value that they can add in terms of quality, operational cost and asset availability. Valve stiction has been identified as a main cause leading to poor performance of process control loops due to oscillation in the process variable. In this work, Gravitational Search Algorithm (GSA) is used to determine the optimal weights of an adaptive Finite Impulse Response Filter (FIR) that acts as a compensator. Computer simulations case studies were conducted to assess the performance of proposed approach.
