unsecnted Kalman Filter

用Cohen--Coon整定公式来求P,PI,PID的个参数，其中Gc是校正器的传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量vars为带迟滞--惯性环节模型的KT τ 输入参量vars为带迟滞--惯性环节的K T ι，已知参数k=vars（1）；T=vars（2）；ι=vars（3）。(With Cohen- Coon tuning formula to seek P, PI, PID' s parameters, which Gc is the corrector transfer function, kp the proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters vars as with hysteresis- inertia model KT τ as input parameters vars with hysteresis- inertia of KT ι, the known parameters k = vars (1) T = vars (2) ι = vars (3).)
