    • A process and apparatus for operating a turbocompressor having an output at an actual value of flow and pressure and a blow-off valve for regulating the output to prevent surging of the output above a surge limit and to prevent a reduction of the output below a minimum value, with a comparing unit for measuring the actual value, and a controller unit for controlling the blow-off valve in accordance with the output of the comparing unit comprising, forming a first difference value between the theoretical value and the actual value, forming a delayed value from the difference value and thereafter forming a second difference value between the delayed value and the first difference value to control the blow-off valve. The apparatus for effecting the process comprises summing units for forming the various difference values, a delay unit for delaying the first difference value and, in one embodiment, a limiter unit for limiting the second difference value which is thereafter added to the theoretical value before the resulting value is applied to the controller unit for controlling the blow-off valve.
    • 一种用于操作具有实际流量和压力值的输出的涡轮压缩机的过程和装置,以及用于调节输出以防止输出浪涌超过浪涌极限并且防止将输出降低到最小值以下的排出阀 值,具有用于测量实际值的比较单元,以及用于根据比较单元的输出控制排出阀的控制器单元,包括:在理论值和实际值之间形成第一差值,形成 延迟值,然后在延迟值和第一差值之间形成第二差值,以控制排出阀。 用于实现该处理的装置包括用于形成各种差值的求和单元,用于延迟第一差分值的延迟单元,并且在一个实施例中,限制单元用于限制第二差值,其后加到第一差值之前的理论值 得到的值被施加到用于控制排放阀的控制器单元。
