Figure 5From: Adaptive control of multiple chaotic systems with unknown parameters in two different synchronization modes Synchronization errors \(\pmb{e_{21}}\) , \(\pmb{e_{22}}\) , \(\pmb{e_{23}}\) , \(\pmb{e_{24}}\) between drive system ( 3.6 ) and response system ( 3.7 ) in (a), and the time response of the adaptive vector parameters \(\pmb{{{a}_{2}},{{b}_{2}},{{c }_{2}},{{d}_{2}},{{a}_{3}},{{b}_{3}},{{c }_{3}},{{d}_{3}},{{r}_{3}} }\) in (b).
