| 中文摘要 |
| PID控制器由于其结构简单和参数整定容易, 具有良好的控制功能, 被广泛应用在工程上的线性确定性系
统中. 但是, 在非线性系统和不确定性系统中, PID控制器由于其固定的控制参数和结构限制, 很难克服系统中内外
干扰的影响, 控制器鲁棒性能较差. 本文按照被控对象中的标称模型设计常规PID控制器优化参数, 对非线性系统
中多个线性化模型和不确定性系统中的不同工作点模型, 设计了一类补偿器, 使得整个闭环系统具有与标称模型下
相同的控制品质. 工程应用例子论证了本文提出的补偿器能提高不确定与非线性系统的控制品质和鲁棒性能. |
| 英文摘要 |
| The PID controller is widely applied in the liner time-invariant plants for all types of industries, due to the
simple structure and easy tuning. However, the poor robustness is found in the application of PID Controller within the timevariant
and non-linear plants, because of the fixed structure and parameters. The study presents a compensator to enhance
control quality and robust performance in time-variant or non-linear plants for the PID controller based on the transfer
function of nominal operation case. Under several optimization criteria, the compensator is designed by the maximum of
gap metric within uncertain or non-linear model, it is shown that the outputs of control system for the different operational
situations are same as the nominal operation cases. Furthermore, the engineering examples confirm the fine control quality
and robust performances of the control systems with the compensator in the time-variant systems. |
