This manuscript proposes a novel technique of synchronization to synchronize four non-identical chaotic systems together. The newly introduced scheme is named as anti-difference quadratic compound synchronization. We have also used the multi-switching of signals to increase the complexity of the proposed scheme. Lorenz, Rössler, and the modified financial systems are taken as drive systems, and the modified Shimizu–Morioko system is taken as the response system to illustrate the obtained results. Lyapunov stability is used to design suitable controllers. Numerical simulations and graphs are presented using MATLAB to verify the theoretical results.
