Abstract
This brief develops a novel fixed-time dynamic event-triggered control design for strict-feedback nonlinear systems with an input dead-zone. Compared with static event-triggered control, a dynamic event-triggering condition is designed to reduce the computation and communication burden. A novel compensation filter is designed to compensate for the input dead-zone and can be utilized to eliminate the influences of input dead-zone on control design. Furthermore, novel command filters (CFs) are introduced to deal with the explosion of complexity. Both the proposed novel compensation filter and CFs can achieve fixed-time performance. The presented method is validated using a jerk circuit system.
