摘要： A surge control system (16) is provided for a compressor (14) which anticipates the actual surge condition and initiates anti-surge protection in proportion to the magnitude of the anticipated surge condition. This is done by providing a feed foward signal (20) to a summing station (48) along with a normally generated surge control line point (44) to offset this point (44) by an amount determined by the feed forward signal (20). This offset point (50) is used as an input to a controller for controlling the bypass valve (28) in a bypass loop (30) around the compressor (14).
摘要翻译： 提供一种用于压缩机（14）的浪涌控制系统（16），该压缩机预测实际的浪涌状况，并且与预期的喘振状况的大小成比例地启动防浪涌保护。 这通过将馈送信号（20）连同正常产生的喘振控制线路点（44）一起提供给求和站（44），以将该点（44）偏移由前馈信号（20）确定的量， 。 该偏移点（50）用作控制器的输入，用于控制围绕压缩机（14）的旁通回路（30）中的旁通阀（28）。

摘要： An adaptive gain surge control system (18) is disclosed for a centrifugal compressor (14) which reacts to both normal and emergency surge conditions by controlling a bypass valve (48) across the compressor (14) inlet and outlet in response to a variable gain (G) determined by the offset (d) of the surge control line from the surge line of the compressor.
