    用局部参数最优化方法设计一个模型参考自适应系统,可调增益的初值Kc(0)=0.2,给定值r(t)为单位阶跃信号,即r(t)=A×1(t)。 要求: 1把连续系统离散化(采样时间可取0.1)。 2编制并运行这个系统的计算机程序(注意调整B值,使系统获得较好的自适应特性)。 3记录ym、yp的曲线 记录kp×kc的曲线 记录广义输出误差e的变化曲线。 4在参数收敛后,让Kp=2变为Kp=1,重新观察Kp×Kc及e的变化曲线。 5找出在确定的B值下,使系统不稳定的A值(阶跃信号的幅值),并与用劳斯稳定判据计算的结果比较。 (With local parameter optimization method to design a model reference adaptive system, adjustable gain initial Kc (0) = 0.2, for a given value of r (t) for the unit step signal that r (t) = A × 1 ( t). Requirements: a continuous system discretization (sampling time of 0.1 preferred). 2 compiled and run the system computer program (Note B to adjust the value of the system to obtain better adaptive characteristics). 3 records ym, yp curve record kp × kc curve records generalized output error e curves. 4 parameter convergence, let Kp = 2 into the Kp = 1, re-observed Kp × Kc and e curves. B-5 to find value in determining the next, making the system unstable A value (step signal of amplitude), and using Routh stability criterion and the comparison of the results calculated.)

  • InvCWT
    This collection of files is an extension of the wavelet software package originally written by Torrence and Compo (http://paos.colorado.edu/research/wavelets/software.html) The main functions are: 1. contwt.m: (continuous wavelet transform). This is essentially Torrence and Compo s wavelet.m with a few modifications (more inputs and outputs for easier access) 2. invcwt.m: inverse continuous wavelet transform.
