Embodiment Construction
[0045] The present invention will be further described below in conjunction with the accompanying drawings and examples. It should be understood that the following examples are intended to facilitate the understanding of the present invention, and have no limiting effect on it.
[0046] Such as figure 1As shown, the iterative learning control method for rehabilitation mechanical devices based on disturbance observers in this embodiment includes the following steps:
[0047] Step 1: Mathematically abstract the rehabilitation mechanical device and establish a linear model of the rehabilitation mechanical device;
[0048] Mathematically abstract the rehabilitation mechanical device and establish a general linear model, which can be specifically described as:
[0049]
[0050] Among them, t∈{0,…,N} represents the sampling moment, N is the sampling period, Indicates the number of iterations to run; x k (t) represents the internal state of the rehabilitation mechanism during ...
