Simulink自带的这个时变传递函数模块(Varying Transfer Function)就是使用的微分方程方法实现的。 2.2 方法二:通过状态空间实现时变传递函数 传递函数还可以转变为状态空间形式,如上述二阶系统可转变为可控标准型状态空间: \[\left\{ \begin{align} & \left[ \begin{matrix} {\dot{y}} \\ {\ddot{y}} \\...
如果是参数是固定几个常数，可以考虑用switch，实在太复杂直接转状态空间自己写函数会快一点。
Varying 2DOF PID Discrete Varying 2DOF PID These blocks are preconfigured versions of the PID Controller and PID Controller (2DOF) blocks. Use them to implement PID controllers in which the PID gains vary with scheduling variables. Varying Transfer Function Discrete Varying Transfer Function Use the...

Compute and plot the describing function for amplitudes varying between 0.1 and 2.1. The describing function is implemented in saturationDF.m. Get A = linspace(0.1,2.1,21); N_A = saturationDF(0.5./A); plot(A, N_A) xlabel('Amplitude') ylabel('N_A(A)') title('Describing Function fo...
A frequency response describes the steady-state response of a system to sinusoidal inputs of varying frequencies and lets control engineers analyze and design control systems in the frequency domain. To understand why the frequency domain is important consider an acoustic guitar. If we place a micro...
Check whether signal is zero Check that absolute value of difference between successive samples of discrete signal is less than upper bound Check that gap of possibly varying width occurs in range of signal's amplitudes Check that one signal is always less than another signal Check that signal fa...
Different simulations were performed by varying the sweep time (1/fp) between 100 ns and 100 μs, where the BW was fixed at 4 GHz according to [KOS 12]. The tag resonator was modeled with an RLC series circuit terminated with a 50 Ω load. Its resonant frequency was 4 GHz with a ...
