【 摘 要 】

References(5)Cited-By(1)This paper describes the study of the gain-maximizing (GMAX) control system in high-order processes. The GMAX system is applied to the process where a high-order linear dynamic element is followed by a static sigmoid function. It regulates the process output at the sigmoid curve’s inflection point, where the static gain becomes maximum. Adaptive broken-line fitting based on a new high-order difference equation is developed. New feedback compensation is also proposed to improve control performance. Computer simulations show that the process output settles quite rapidly to the maximum-gain level, and reliable GMAX control can be achieved.
