双线性系统的状态反馈预测控制

State feedback predictive control on bilinear systems

针对可输入输出(I/O)精确线性化的双线性系统,提出了一种直接的预测控制算法。这种算法应用状态反馈预测控制算法的思想,无需对双线性系统进行线性化,因而避免了线性化后再引入线性控制算法进行控制而带来的复杂运算,并且可以提高控制系统抑制未知干扰的能力,增强了系统的鲁棒性。给出了算法的使用条件和推导过程。仿真结果表明,新的算法控制效果良好。

A direct predictive control approach for the bilinear system that can be exactly linearized is proposed. The approach, based on state feedback predictive control eliminates the need of system linearization, thus complicated operation resulting from utilizing other linear control methods after linearization can be avoided. Simulation results show a good controllability of the proposed approach.\;
