| 摘 要： | 研究具有二次型性能指标的离散时滞双线性系统最优控制问题。对既带有时间超前项又带有时间滞后项的非线性两点边值(TPBV)问题,通过逐次逼近算法(SAA)构造不含超前滞后项的线性非齐次TPBV问题迭代序列。最优控制律由精确的线性反馈项和非线性时滞补偿序列的极限项组成。取补偿项序列的有限次迭代值,获得次优控制律。通过仿真,验证算法的有效性。

| Abstract: | The paper studies the quadratic optimal control problem of discrete time delay bilinear systems.By using a successive approximation approach(SAA),the nonlinear two point boundary value(TPBV) problem with time-advance and time-delay terms is transformed into a linear inhomogeneous TPBVproblem iteration sequence without advance and delay terms.The optimal control law consists of an accurate linear feedback term and a nonlinear delay compensation term that is the limit of an adjoint vector sequence.By taking a finite-time iteration of the compensation sequence,a suboptimal control law is obtained.The validity of the presented approach is demonstrated by simulation example. |
