在生产过程中,单回路自动调节系统用得最多。一个系统在运行一段时间后,由于调节器元器件参数变化,会使系统的调节品质受到影响,这时应对调节系统重新整定。调节系统整定常采用以下几种方法。1.经验法对于不同的调节对象,其整定值有一个经验值供参考。对液位,δ=20～80％;对压力,δ=30～70％,T_i=0.4～3分;对流量,δ=40～100％,T_i=0.1～1分;对温度,δ=20～60％,T_i=3～10分,T_D=0.5～3分。调试步骤:把调节器T_i=∞,T_D=0,使之为P作用;按上述经验值试凑δ值,使系统过渡过程为4:1衰减振荡;把δ增加10～20％,加入积分,使之仍为4:1衰减。对温度系统,应加微分,T_D=
In the production process, single-loop automatic adjustment system with the most. A system running for some time, due to changes in the parameters of the regulator components, the system will affect the quality of the regulation, then adjust the system to be re-tuning. Adjust the system setting often use the following methods. 1. Experience for different regulatory objects, the setting value has an empirical value for reference. For the liquid level, δ = 20-80%; for the pressure, δ = 30-70%, T_i = 0.4-3; for the flow rate, δ = 40-100%, T_i = 0.1-1; 20 to 60%, T_i = 3 to 10, and T_D = 0.5 to 3. Debugging steps: the regulator T_i = ∞, T_D = 0, so that the P role; according to the experience of trial and error value δ test, the system transition process for the 4: 1 decay oscillation; the δ increased 10 ~ 20% , So that it is still 4: 1 attenuation. On the temperature system, should be differentiated, T_D =
