Obtain according to least square fitting is done.For example, there are a=3.24b=0.19, i.e. t to certain 200MW resuperheat fuel oil consump-tionr=
(3.24×λ+0.19)×s.
Rule 2：Lambda parameter can affect the overshoot of system, but the phenomenon of non-overshoot occurs in system within the specific limits.If
The collection of all lambda parameters of system non-overshoot is made to be combined into A, then A={ λi,λi∈(λmin,λmax)}.According to operating experience, as λ ＜ λmin
When, system response is too fast, and shake occurs in uphill process, and so as to produce overshoot, now overshoot can increase with the reduction of λ
Greatly.As λ ＞ λmaxWhen, cause system time constant to increase as λ increases, the response of system is slack-off, and the bandwidth of controller increases,
The damping ratio of system diminishes, and system will not produce overshoot.
Rule 3：When λ value changes and makes system produce overshoot, the system output pulsation of steam turbine side is than boiler side
System output more more sensitive to model error.
Rule 4：When the load, the original dynamic model parameters of system are changed therewith, in this case, λ
Parameter value is improper to cause system unstable.Parameter lambda value is bigger, and the robustness of control system is better.
