2. Parameter *m* in *W*T

To analyze the influence of the parameter *m* on weighting function *W*T, the other parameters in the weightings were kept unchanged. By changing *m* from 0 to 30, the dynamics were calculated by the step response, which is shown in Figure 9. With the increase in parameter *m*, the settling time almost remained unchanged first and then decreased quickly. Then, the settling time increased with the increase in parameter *m*. The overshoot decreased with the increase in parameter *m*, and then almost remained

unchanged regardless of how the parameter *m* increased. Meanwhile, the steady-state error remained unchanged first and then fluctuated at a relatively high value.

3. Parameter *n* in *W*T

By varying the parameter *n* from 0 to 450, the dynamics were calculated via the step response correspondingly, which are shown in Figure 10. It is seen that with the increase in parameter *n*, the settling time and steady-state error varied in a very small range, which could be viewed as unchanged. Meanwhile, the overshoot increased with the parameter *n*.
