本文针对一类单输入单输出(SISO)线性时变模型跟踪控制系统,提出一种参考模型设社方法。该方法由如下的两个步骤构成:首先,根据闭环系统的动态性能指标要求,如对闭环系统的极点配置的要求,来确定参考模型中的系统矩阵;其次,根据闭环系统的稳态性能指标要求,如要求参考模型的稳态输出准确复现参考模型的输入(即期望输出或系统指令输人)、要求系统的稳态输出或状态准确复现参考模型的稳态输出成状态等,来确定参考模型中的控制增益矩阵。最后,通过仿真其例验证了本文方法的正确与有效。
In this paper, a type of single input single output (SISO) linear time-varying model tracking control system is proposed. The method comprises the following two steps: Firstly, the system matrix in the reference model is determined according to the requirements of the dynamic performance index of the closed-loop system, such as the requirements of the pole placement of the closed-loop system; secondly, based on the steady- Requirements such as requiring the reference model’s steady-state output to accurately reproduce the input of the reference model (ie expected output or system instruction input) require the system’s steady-state output or state to accurately reproduce the steady-state output of the reference model into the state, etc. Determine the control gain matrix in the reference model. Finally, we verify the validity and effectiveness of our method by simulating the examples.
