摘　　要：系统参数发生跳变时，为了解决多变量系统暂态响应变差的问题，提出一种基于多模型切换的鲁棒自适应控制器。该控制器由多个鲁棒自适应控制器组成，鲁棒自适应控制器保证系统存在未建模动态时能够使自适应系统稳定运行，引入的多模型策略保证系统参数跳变时具有良好的暂态性能。仿真结果表明，所提出的多模型鲁棒自适应控制器能够加快系统的响应速度，提高系统的暂态性能。A multivariable robust adaptive controller was presented using multiple models. This controller improves the transient response, when the parameters of the multivariable system change abruptly. It is composed of multiple robust adaptive controllers. Robust adaptive control assures stable adaptive control, and multiple model control is used to improve the transient response and system performance when the parameters of the system are changing abruptly. As a result, simulation results show that the proposed multiple model robust adaptive controller can mend system response speed and improve transient performance.
