Embodiment Construction
[0023] figure 1 It is a flowchart of an embodiment of the present invention, which includes the following steps: S1, sampling the input and output of the controlled system, and utilizing the identification algorithm to obtain the continuous-time model of the system; S2, constructing a continuous-time filter according to the continuous-time model; S3 . According to the coefficients in the continuous-time filter equation and the adoption time of the discrete system, a partial differential equation method is used to calculate the discrete-time filter coefficient matrix; S4. Constructing a discrete-time filter structure.
[0024] In step S1, the continuous time model is x · ( t ) = Ax ( t ...
