中文摘要
      连续搅拌反应釜(CSTR)是化工过程工业中常用的反应容器.为进一步提升CSTR系统的动态性能和静态性 能, 本文针对一类含有未知干扰的CSTR系统提出一种基于预定义时间的滑模控制算法.为使CSTR系统在预设时 间内稳定,并解除系统初始状态对稳定时间的约束,基于预定义时间控制理论建立了系统稳定时间和控制参数的显 示关系;为减小滑模控制器的抖振,采用tanh函数代替传统符号函数sgn设计控制律;采用MATLAB仿真实验验证所 设计控制方案的有效性和可行性;通过与现有有限时间控制方法进行仿真结果对比,检验本文设计方法的优越性. 研究结果表明,本文方法在保持良好静态性能的同时,具有更强的抗干扰能力和更快的收敛速度.
英文摘要
      Continuous stirred tank reactor (CSTR) is a common reaction vessel in chemical process industry. In order to further improve the dynamic and static performance of CSTR system, this paper proposes a sliding mode control based on predefined time for a class of CSTR system with unknown disturbance. In order to make the CSTR system stable within the preset time and release the constraint of the initial state of the system on the stability time, the display relationship between the system stability time and the control parameters is established based on the predefined time control theory; In order to reduce chattering of sliding mode controller, tanh function is used instead of sgn function to design control law; MATLAB simulation experiment is used to verify the effectiveness and feasibility of the designed control scheme; Compared with the existing finite time control method, the simulation results verify the superiority of the design method in this paper. The research results show that the method in this paper has stronger anti-disturbance ability and faster convergence speed while maintaining good static performance.
