Abstract
A control method for converting time-varying system into a time-invariant system, comprises: using (n−1)th to 0th order signals of an nth-order time-varying, system as feedback to set up a closed loop control for the time-varying system; acquiring real-time values of the coefficients in each order of the time-varying system through a sensor, and calculating variations between the real-time values and the initial values of the coefficients in each order through a controller; amplifying and summing the parameters of every order to obtain a measured disturbance; inputting the measured disturbance, a control signal from a controller and an nth-order signal into an extended state observer through to estimate the rest disturbance; summing up the measured and estimated disturbances to obtain total disturbances; and adjusting the above parameters in each order through the controller to convert the time-varying system into the tune-invariant system.
