摘 要：正Aiming at the target tracking problem in fire control system,the satisfactory discrete-time bias-allowable estimator is investigated in this *** fire control system,the smoothness of forecasting target future positions is an important factor that affects shooting *** lower order system model to estimate target state is a common method of smoothly forecasting the future position,which could produce system bias when the target is suddenly *** important index in constraining system error called steady error coefficient is introduced into the performance index set with error variance upper bound and area pole *** the maneuvering intensity of target is finite,an iterative algorithm in terms of linear matrix inequalities（LMIs） is proposed to solve the satisfactory bias-allowable estimation *** proposed bias-allowable estimator can ensure the accuracy and smoothness of the estimation output by using a lower order system *** an example is presented to demonstrate the obtained results.
