Demonstration of A Hyberid Intelligent Control StrategyPosted by actapress on Oct 22, 2010 in Control and Intelligent Systems | 0 comments
Many industrial facilities utilize pressure control gradients to prevent migration of hazardous species from containment areas to occupied zones, often using proportional-integral-derivative (PID) control. Within these facilities, PID control is often inadequate to maintain desired performance due to changing operating conditions, a common issue in process applications . As the goal of the heating, ventilation and air-conditioning (HVAC) control system is to optimize the pressure gradients and associated ﬂows for the plant, linear quadratic tracking (LQT) provides a time-based approach to guiding plant interactions. However, LQT methods are susceptible to modelling and measurement errors, and therefore a hybrid design using the integration of soft control methods with hard control methods is developed and demonstrated to account for these errors and non-linearities.
