In this article, the event-triggered adaptive output feedback control of multivariable system under nonsmooth actuator nonlinearities, including deadzone, backlash, and hysteresis is investigated. The nonsmooth actuator nonlinearities are handled with a unified framework by modeling them with a time-varying disturbance and a control input. With an event-triggered mechanism and an one-parameter estimation approach, the communication consumption for the control of multivariable system is significantly reduced. It is shown that all signals in the closed loop system are bounded. The Zeno behavior is also avoided. The simulation results demonstrate the effectiveness of the control scheme.
