    • 摘要: LED是非线性半导体器件,针对其线性模型难以建立而无法用线性系统理论设计控制器的问题,以Boost型LED恒流驱动电路为例,提出了一种逆系统解耦双电流环控制方法。在建立了系统大信号平均模型的基础上,采用双电流环控制结构,基于逆系统理论对内电流环和外电流环进行解耦,并分别将其补偿为一阶积分子系统,进而采用最优控制理论对线性子系统进行控制器设计。仿真结果表明,所提控制策略能使Boost型LED恒流驱动电路具有良好的稳态和动态性能。最后,设计了一台实验样机,从电学和光学两个角度进一步验证了所提控制策略的正确性和有效性。

    • 摘要: For the purpose of effective diagnosis of a class of nonlinear system with the time-varying failure of the actuator, a method of the fault accommodation was proposed based on time-varying gain extended state observer ( ESO ) for the inverse system. Firstly, the traditional constant gain ESO was improved by using a time-varying gain design method, which guaranteed that the "peaking value"problem in the initial phase of the state and fault estimation was effectively eliminated. Secondly, the nonlinear system was linearized to the corresponding linear system based on the compensation and regulation of the fault estimation value for the original system and the introduction of the inverse system. At this time, the system not only possessed fault-tolerant ability, but also possessed the pseudo linear characteristic whether failures occurred or not. And then, the robust guaranteed cost control was designed . The system possessed good performance as well as the robustness to the inverse modeling errors by using the same controller. Finally, a simulation example shows the effectiveness of the proposed approach.%为了对一类非线性系统执行器时变故障进行有效诊断,研究了一种基于变增益扩张状态观测器的逆系统故障调节方法.首先,通过一种时变增益的设计方法,来改进传统的恒增益扩张状态观测器,有效消除了在状态及故障估计初始阶段的"峰值"问题;其次,在依据故障估计值对原系统进行补偿调节的基础上,借助于逆系统的引入,对原非线性系统线性化,在使系统能对故障容错的同时,确保了系统无论故障发生与否的不变伪线性特性,进而又为其设计了鲁棒保性能控制,从而以不变的控制器使得系统始终具有了良好的性能及对逆建模误差的鲁棒性;最后,仿真算例对比验证了该方法的有效性.

    • 摘要: For the vibration suppression of active magnetic bearing (AMB) high-speed flywheel rotor system,a control strategy based on inverse system decoupling and improved two-degree-of-freedom (2DOF) control was proposed in this paper.The AMB flywheel rotor system was decoupled by the inverse system method firstly,so that the AMB flywheel rotor system,which was a nonlinear,strong coupling system,was decoupled into four independent subsystems.Then,the decoupled subsystems were adjusted by the improved 2DOF controller,which can regulate the performances of set-point tracking and disturbance rejection,respectively.In the improved 2DOF controller,the damping control signal was obtained by velocity estimator,so that the ability of against noise can be improved.The stability,setpoint tracking and robustness of control strategy proposed were analyzed in theory,and its ability and effectiveness to control the vibration of AMB high-speed flywheel rotor system were further investigated by simulations and experiments.It is shown that the control strategy proposed can stably suspend the AMB high-speed flywheel rotor system and effectively suppress its vibrations,with the advantages of high stability,strong robustness,and good ability of against noise.%针对电磁轴承高速飞轮转子系统的振动抑制问题,提出了一种基于逆系统解耦和改进型二自由度控制的方法.首先采用逆系统方法对电磁轴承飞轮转子系统进行解耦,将非线性、强耦合的电磁轴承飞轮转子系统解耦为四个彼此独立的子系统,再用改进型二自由度控制器对解耦后的子系统进行整定,使控制系统的设定值跟踪及外扰抑制特性能够分别调节,并通过速度观测器获取阻尼控制信号,增强系统的抗噪声能力.从理论上分析了所提出控制算法的稳定性、设定值跟踪性能及鲁棒性,并对其性能进行了仿真和实验验证.结果表明,该文提出的控制算法能够使飞轮转子稳定悬浮并有效抑制其振动,具有稳定性好、鲁棒性强、抗噪声能力强等优点.
