摘要
基于离散脉冲正交函数及其性质,建立了一种新的附加系统方法,以实现双线性系统的预测控制方案。这种设计方法避免了非线性优化问题,所有的运算均为代数计算,使设计过程得以简化。对合成氨反应器仿真结果,证明了本法的有效性。
A new approach based upon discrete pulse orthogonal functions (DPOFs) to design predictive controller for bilinear system was developed. In the new design procedure, it is not necessary to calculate the nonlinear optimization problem because all calculations could be summed up as algebraic relations. The final control action becomes the solution of a least-square problem which contains the adjustable parameters, therefore the tuning is also much simpler. Two examples illustrate that the method is effective.
