针对海上风力机在高频风速扰动和通信资源受限条件下存在的控制效率低与通信负载重的问题,提出了一种基于T-S模糊模型的自适应事件触发控制方法。通过构建不同风速工况下的T-S模糊增量模型,实现对风力机系统非线性动态特性的有效建模。控制器采用状态误差驱动的事件触发机制以降低通信频率。基于Lyapunov稳定性理论,通过求解线性矩阵不等式获得相关增益完成控制器的设计。设计中引入H∞性能指标以提高系统对风扰动影响的抑制能力。仿真结果表明,所设计的控制器能减小阶跃风和湍流风等典型风扰动给系统带来的影响,使风力机功率稳定在一定范围内,同时显著降低系统的通信负载。
An adaptive event-triggered control method based on T-S fuzzy model was proposed to address the problems of low control efficiency and heavy communication load of offshore wind turbines under high-frequency wind speed disturbances and limited communication resources. By constructing T-S fuzzy incremental models under different wind speed conditions
the nonlinear dynamic characteristics of wind turbine system were effectively modeled. The controller adopts a state-error-driven event-triggered mechanism to reduce the communication frequency. Based on Lyapunov stability theory
the relevant gains were obtained by solving linear matrix inequalities to complete the controller design. The H∞ performance index was introduced in the design to enhance the suppression capability against wind disturbances in system. Simulation results demonstrate that the designed controller can mitigate the impacts of typical wind disturbances including step wind and turbulent wind on the system
stabilize the output power of the wind turbine within a specified range
and significantly reduce the communication load of system.
