Matlab evalfr, evalfr is a simplified version of freqresp meant for quick evaluation of the response at a single point. To obtain the magnitude and phase data as well as plots of the frequency response, use bode. matlab. Use freqresp to compute the frequency response over a set of frequencies. evalfr is a simplified version of freqresp meant for quick evaluation of the system response at any point in the complex plane. noutputs number of outputs. User's Guide for the Control System Toolbox, a powerful MATLAB-based collection of algorithms for control system design, analysis, and modeling. ninputs number of inputs and p = sys. evalfr 是 freqresp 的简化版本,用于快速计算复平面中任意点的系统响应。要计算一组频率下的系统响应,请使用 freqresp。要获取幅值和相位数据以及频率响应图,请使用 bode。 control. . To evaluate system response over a set of frequencies, use freqresp. evalfr(sys, x, squeeze=None) [source] Evaluate transfer function of LTI system at complex frequency. Returns the complex frequency response sys(x) where x is s for continuous-time systems and z for discrete-time systems, with m = sys. To evaluate at a frequency omega in radians per second Use freqresp to evaluate the system response over a grid of frequencies. This document covers topics like LTI models, time and frequency responses, control design tools, and model analysis. evalfr control.
