In order to ensure a good mode following and to aid the tracking performance of the flight control system, the first and second-time derivatives of the desired model response, computed by a model reference (MR) system, are either directly used as feedforward signals for the outer loop or are additionally transformed for the inner-loop by using an incremental nonlinear dynamic inversion (INDI) grounded approach to transform the signals based on known systems kinematics. In order to uniformly handle the overactuated flight vehicle in both mission model and during the transition, an operation mode-based weighted incremental linear control allocation approach is applied for safe operation.

Notably, the zoom variable of this quantizer can be discretely adjusted. Specifically, the interval between two consecutive adjustments of the zoom variable has a positive lower bound, which contributes to reduced energy consumption. Next, we consider unbounded time delays that may lead to packet loss in networked control systems with limited bit rate. We prove that the system stabilization relies on a mild assumption on packet loss frequency.

In the related results, the controller functions are required to obey global Lipschitz condition for the suppression of sampling/execution error, and the drift and/or diffusion coefficients of the stochastic systems are restricted to polynomial or, even, linear growth. These limitations deserve overcoming for enlarged applications. To this end, a distinct framework of time/event-triggered controls is established for stochastic systems, targeted at exponential stabilization. Specifically, inclusive Lyapunov-type feasibility conditions are proposed by capturing the effect of sampling/execution error and distinguishing the role of system nonlinearities. Particularly, different from the related results, the evolution of sampling/execution error is subtly exploited via Lyapunov functions to reveal the dynamic interaction between the sampling/execution errors and system state. Then, time-triggered exponential stabilization via sampled-data controller is achieved not only in the moment sense but also in the almost sure sense. Accordingly, Lyapunov function based analysis is performed for the composite dynamics of system state and sampling error, confronted with the coupling of discontinuous and stochastic features. To further reduce execution, periodic event-triggered control is exploited to achieve exponential stabilization for stochastic nonlinear systems, by virtue of the relation with the dynamic evolution under sampled-data control.
