[0045] A simulation case is given below to verify the effectiveness and correctness of the control method proposed by the present invention.
[0046] When γ=100, σ=10, and no control is applied, the dynamic model of n permanent magnet synchronous motors controlled exhibit chaotic dynamic behavior. When the number of permanent magnet synchronous motors is n=100, the simulation results without any control are as follows Figure 1-2 shown.
[0047]The results show that when no control is applied, the state variables of all permanent magnet synchronous motors exhibit a disorganized state. Therefore, in order to achieve coordinated operation of all PMSMs, a suitable controller needs to be designed.
[0048] Randomly choose a small-world network with n=100 nodes. controller and adaptive law The parameter selection of is: coupling strength c=1, inner coupling matrix Γ=diag(1,1,1), and the initial value of the state variable is in the interval (0,80), (0,30) and (0,10) Ran...
