random_band is the main program and it outputs a test signal which has a constant level. The instanatenous frequency varies randomly within the specified Nth octave band range.The program outputs three plots: time record of the instantaneous frequency, time record of the instantaneous level, and...

- This demo supports R2006a -> R2010aSimulink plant and controller models are used with LEGO's latest high-tech robot (ARM-based LEGO Mindstorms NXT) to illustrate industrial application of Model-Based Design with Production Code Generation. Take note of the model architecture and component...

The program 'Efinder' numerically solves the Schroedinger equation using MATLAB's 'ode45' within a range of energy values. By taking advantage of the dramatic endpoint behavior of the resulting wave solutions, 'Efinder' determines the eigen energies to any accuracy needed.This program has been...

Estimating plant model parameters and tuning controllers are challenging tasks. Optimization-based methods help to systematically accelerate the tundlTCing process and let engineers tune multiple parameters at the same time. Further efficiencies can be gained by running the optimization in a...

Most PID tuning rules are based on first-order plus time delay assumption of the plant hence cannot ensure the best control performance. Using mordern optimization techniques, it is possible to tune a PID controller based on the actual transfer function of the plant to optimize the closed-loop...

How can we characterize an image, and does the same characterization yield the same result? In this work, we study one possible characterization, distribution metrics. That is, we assume the desired region of interest has a different probability distribution from its corresponding background....

Gas absorption is a very ubiquitous unit operation in any chemical plant. It has in common with liquid-liquid extraction that there are two carrier streams and one solute to be partioned between them. Here, we use the McCabe and Thiele graphical method to study the separation of acetone from air....

Unknown Input Observers(UIO) are used in model based FDI schemes to reduce or almost eliminate the effect of unknown disturbances on the plant/system.Further they can be used to generate residuls that are insensitive to unknown disturbances or noise, thus lower the false alarm rate.For isolation...

Given a continuous-time system with parameters, can we find the range (or intervals) of the parameters where the system is stable?When the system model is written with the Laplacian transform, the question is equivalent to finding all the roots of a parameterized polynomial where the real parts...

The purpose of Input Shaping is to filter out big changes (typically steps) in the reference signal of a closed-loop system which excite all the modes of the plant causing relevant snap overshoots and oscillations in the response.The underlying working principle is to apply the step in subsequent...

R = RCR(S) computes the semi-edge-length of the mean-centered hypercube with 95% probability given S, which is either a covariance matrix or a vector of standard deviations from a multivariate normal distribution. If S is a real, nonnegative vector, RCR(S) is equivalent to RCR(DIAG(S.^2)). Scalar...

Design of a robust digital controller with PPR toolboxThis script shows the basic steps for the "digital two degrees of freedom controller" (2DOF) design with the PPR toolbox.The illustration of our methodology is based on a difficult plant control. To get a 2DOF controller, only 2 "high level"...

IMSHADE will plot a matrix representing topography as a 3-component color image, with intensity proportional to the magnitude of the topographic slope of each pixel. Optionally, it can take an argument for lighting angle to use the directional slope.The current colormap will be used, but future...
