Nonlinear H{sub}∞ Control of Neutralization Processes

摘要

In this paper, the nonlinear robust control problems for neutralization processes are discussed. The main control design method is based on nonlinear H{sub}∞ control. To overcome the difficulty of nonlinear Hamilton-Jacobian-Issac's inequalitysolving problem, a set of suitable penalty variables of the process is chosen. The controller is synthesized by only solving an algebraic matrix Riccati inequality. To overcome the influence of the external disturbance, the nonlinear H{sub}∞ controlleris modified by adding an extra compensation term. The validity of the proposed controller is verified by simulations.
