Abstract: Based on the semi-tensor product of matrices and the real vector representation of reduced biquaternion, the problem of reduced biquaternion regulating equations A1X-A2XB=C is transformed into a matrix equation on real number field without constraint, and then the (anti-)Hermitian solution of reduced biquaternion regulating equations is obtained by using real matrix equation. The effectiveness of this method is verified by numerical experiments. Finally, this method is applied to the continuous zeroing dynamics design of time-varying linear systems.

Key words: regulating equation, semi-tensor product of matrices, real vector representation, reduced biquaternion matrix
