Cascade Fuzzy Self Adaptive PID Controller for Inverse Response of Boiler Drum Level
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2015, Vol 2, Issue 5
Abstract
In this paper, we are presenting new method with Cascade Fuzzy Self Adaptive PID Controller for Inverse response of the boiler drum water level. Conventional PID control System cannot reach a satisfactory result in Boiler drum water control system. Self tuning is that plant to be controlled often changes from time to time. This is especially true, if the plant is a unstable system with changing operation points then cascade fuzzy self adaptive PID provides effective method for adaptation of such changes. A cascade fuzzy self adaptive PID controller for boiler drum level control is proposed to improve time domain characteristics. In this paper, output of first fuzzy self adaptive controller is given to second self adaptive controller as a set point. From simulation, the performance of cascade self adaptive fuzzy PID controller is better than self adaptive fuzzy PID controller which improves time domain characteristics. MATLAB simulink tool is used to simulate cascade fuzzy self adaptive PID and self adaptive fuzzy PID control system
