► A system composed of cross-flow-water-turbine-based twin vertical towers is studied. ► The angular position synchronization of the two towers is ensured by control action. ► This approach is similar to the phase-locked loop techniques used in electronics. ► Real-time experiments on a power hardware-in-the-loop simulator have been carried out. ► The results sustain the reliability and effectiveness of the approach.
