Garbage Disposal

The garbage disposal system is not a very large system,but it is a complex system..You need to take different control strategies according to different control objects, belonging to the control problem of the complexity of the uncertainty of the object (or process). Conventional control methods (such as PID, etc.) is difficult to implement effective control of such object.It is necessary to explore more effective control strategy. The paper briefly discusses the problem of intelligent control of the garbage disposal systems based on DCS.

Heat Transfer Theory

Coal anode baking temperature system is a MIMO control system which is nonlinear and has cross-coupling and time-delay. The thermal model and flue model before are usually created based on hydrodynamics and heat transfer theory which take long to do the calculation or have ill conditions sometimes. The PID control systems based on the two mechanism models do not yield satisfactory results. In order to control the baking temperature accurately, an intelligent control model based on GA-NN with the aim of improving control precision of baking temperature of carbon anode is established by gathering the real data from anode baking furnace used for initial predictive models. A new GA-NN predictive control system is thus realized for the control of anode baking temperature of which the simulation and real control results showed that the system is efficient and effective with better control precision and robust properties than tradition PID control systems.

Steady State Performance

A STATCOM system is presented in this paper applied for compensation of displacement power factor under distorted mains voltage conditions. The developed STATCOM control system consists of two regulating loops - DC link voltage control loop with anti-windup PI controller and the current control loop with a feed-forward PI controller. The simulation results indicate that the developed control system performs well, ensuring displacement power factor compensation with good transient and steady state performance even under significantly distorted grid voltage conditions.
