This paper proposes an event-triggered tracking control scheme of the nonstrict-feedback nonlinear systems working in both sensor-to-controller (SC) and controller-to-actuator (CA) channels. Aiming at the problems of “algebraic loop” and “jumps of virtual control laws (JVCL)” arising in the backstepping-based event-triggered control (ETC), this paper incorporates the bounded property of basis functions of fuzzy logic systems (FLS) to direct adaptive control, and puts forward a novel method through fabricating undetermined virtual control laws. To utilize the unoccupied communication channel produced by ETC, this paper raises a novel ETC working mechanism called “separate state transmission”. Not like traditional ETC, the states herein are not transmitted in a cluster, which avoids the huge occupancy of network at the triggering instant. The separation is achieved by constructing a cumulative triggering condition. Under the assumption of the compact set of states, it proves all the tracking and estimation errors are ultimately bounded. Simulation verifies the feasibility of the entire work.
