1 Erratum to: Chin. J. Mech. Eng. (2015) 28(4) DOI 10.3901/CJME.2015.0202.053
The original version of this article unfortunately contains a mistake. The presentation of Eq. 8 is incorrect. The corrected equation is given below.
$$\begin{aligned} G & = \mathop {\arg \hbox{max} }\limits_{{G_{n} }} \Bigg\{ {\lg P(\varvec{x}|\lambda_{{n,i_{m} }} ) + \lg P(\lambda_{{n,i_{m} }} |G_{n} )} \\ & \quad + {\lg P(\varvec{y}|v_{{n,j_{m} }} ) + \lg P(v_{{n,j_{m} }} |G_{n} ) + \frac{1}{T}\lg \sum\limits_{t = 1}^{T} {P_{t} (G_{n} |\varvec{z})} } \Bigg\}, \\ \end{aligned}$$
