Abstract :
Hammerstein models are popular in describing nonlinear chemical processes. The general control strategy for Hammerstein models is the nonlinearity inversion method, which is unfortunately inapplicable to Hammerstein systems with input multiplicity. To overcome this difficulty, a Multi-PID control approach is proposed. Thus, a complex control problem is solved by a conventional and easy control strategy. A Heat Exchanger process is simulated to demonstrate the effectiveness of the Multi-PID control approach.
