The problem of satisfactory PID control for a class of stochastic systems with constraints on dynamic error coefficient, steady-state output variance and relative stability margin is considered.

As the result of simulating finished with MATLAB, clear prior knowledge and anticipated result of calibrating dynamic error coefficients of accelerometer on three-axis turntable are obtained.

The star point of the dynamic star simulator's showing grid is measured, and the position error correction factor of each star point is calculated.
