Tab.1 CTPS control strategy and power transfer model

模式 控制策略 Dφ = D2模式 $ {D_1} = \dfrac{{{k^2}}}{{{k^2}+k+1}} - \dfrac{k}{{{k^2}+k+1}}\sqrt {1 - \dfrac{{{p_{{\text{av}}}}({k^2}+k+1)}}{{2k}}} $ $ D_{0}=D_{2}=1+k\left(D_{1}-1\right) $ $ D_{1} \in\left[\dfrac{k-1}{k}, \dfrac{k^{2}}{k^{2}+k+1}\right] $ $ p_{{\mathrm{av}}}=\dfrac{2 k}{k^{2}+k+1}-2\left(k^{2}+k+1\right)\left(D_{1}-\dfrac{k^{2}}{k^{2}+k+1}\right)^{2} $ Dφ = 0模式 $ {D_1} = 1 - \sqrt {{p_{{\text{av}}}}/(2k - 2)} $ $ D_{2}=1+k\left(D_{1}-1\right), D_{\varphi}=0 $ $ D_{1} \in\left[\dfrac{k-1}{k}, 1\right] $ $ p_{{\mathrm{av}}}=2(k-1)\left(1-D_{1}\right)^{2} $
