针对现代控制系统不确定性的问题,基于保护映射理论提出了一种新的鲁棒控制方法.利用保护映射理论,构建控制器增益与闭环系统极点间的联系,通过配置闭环系统极点,改善控制系统的动态特性和稳态性能,以满足期望的性能指标.整个设计过程中控制器结构固定,只需一个初始增益,即可实现系统的鲁棒控制.仿真研究显示对含参数变化的2阶系统模型,该方法能够自适应地获取满足整个变化系统控制性能的控制器增益,同时Monte Carlo随机试验表明了系统参数随机变化下,所求控制增益仍满足系统控制性能要求,从而保证了控制过程的鲁棒性.
Aiming at the problem of uncertainty of modern control system, a new robust control method is proposed based on the protection mapping theory. By using the protection mapping theory, the connection between the gain of the controller and the poles of the closed-loop system is established, and the poles of the closed- The dynamic characteristics and steady-state performance of the system to meet the desired performance.Controller structure is fixed throughout the design process, with only an initial gain, the robust control of the system can be achieved.The simulation shows that for the second order The system model can adaptively obtain the controller gain that satisfies the control performance of the whole system. The Monte Carlo random test shows that the control gain still satisfies the system control performance under the random change of the system parameters, so as to ensure the control process Robustness.
