This paper considers the prescribed performance tracking control problem for strict-feedback nonlinear systems with asymmetric output constraints. A new performance function is constructed to achieve the asymmetric prescribed performance control with the characteristic of the asymmetric output constraint consideration. To save the communication resources in the controller-to-actuator channel, a relative threshold event-triggered mechanism is developed. Then, an adaptive fuzzy event-triggered control strategy is designed by using the asymmetric performance function. It enables that the tracking error can be driven to the preset region in the pre-given finite time and the tracking error satisfies the asymmetric constraint at the same time. In addition, all signals of the resulting closed-loop are bounded and the Zeno behavior is excluded. Finally, the effectiveness of the designed strategy is checked by a numerical simulation with comparisons.

间歇通信下非线性系统的非对称规定性能控制

本文考虑具有不对称输出约束的严格反馈非线性系统的规定性能跟踪控制问题。考虑非对称输出约束的特点，构造了一种新的性能函数来实现非对称规定性能控制。为了节省控制器到执行器通道中的通信资源，开发了相对阈值事件触发机制。然后，利用不对称性能函数设计了自适应模糊事件触发控制策略。使得跟踪误差能够在预先给定的有限时间内驱动到预设区域，同时跟踪误差满足非对称约束。此外，所得闭环的所有信号都是有界的，并且排除了 Zeno 行为。最后，通过数值模拟和比较来检验所设计策略的有效性。
