摘要：

In this paper, the dynamics of organic Rankine cycles (ORCs) in waste heat utilizing processes is investigated, and the physical model of a 100 kW waste heat utilizing process is established. In order to achieve both transient performance and steady-state energy saving, a multivariable control strategy for the waste heat recovery system is proposed by incorporating a linear quadratic regulator (LQR) with a PI controller. Simulations demonstrate that the proposed strategy can obtain satisfactory performance. (C) 2012 Elsevier Ltd. All rights reserved.
