A simple adaptive control strategy for temperature trajectory tracking in batch processes

In this paper, a simple adaptive control strategy is suggested for temperat ure tracking control of batch processes. A nonlinear controller, which is i n structure very simple and consists of a single parameter, is proposed. To enable this controller to control a batch process adaptively, a simple par ameter tuning algorithm is derived based on the Lyapunov stability theorem. The proposed adaptive control scheme is directly operational, which does n ot depend on process model and the only a priori process information requir ed is the system response direction. To demonstrate the effectiveness and a pplicability of the proposed scheme, illustrative examples are provided. Ex tensive simulation results reveal that the proposed adaptive control strate gy appears to be a simple and effective approach to batch process control, which provides robust control despite the wide range of operating condition s and nonlinear dynamics of the system.
