ANALYSIS OF CONTROL CHARACTOR OF REPMSM AND MINIMUM CURRENT CONTROL METHOD

摘要

(1) Using pere unit system, I_a = f(k) as ρ=1. 2, 2. 0, 3. 0 is showed clearly, figure 3 showed φ=f (k) , ψ=f (k), θ=f (k ) as ρ=2. 0. It' s a help to undstand the operation of REPMSM.rn(2) "I=I_(min)" lies bewteen "cosφ=1" and "I_d = 0", for any givet load and p, this means, the error among them is influrced by the load and the parameter p.
