Fast Deconvolution This function deconvolves one extremely large vector out of another extremely large vector very quickly. Enormous gains in speed are due to the use of two fft's and an ifft. To find out how to use this program, put it in you 'work' folder and type "help fdeconv".

Condor Optimizer CONDOR is a new optimizer whose aim is to find the minimum x* of an objective function F(x) (x is a vector whose dimension is between 1 and 150) using the least number of function evaluations of F(x). It is assumed that the dominant computing cost of the optimization process is the time needed to...

Permanent Magnet Synchronous Motor Drives The advantages of vector control provide variety of control choices in the PMSM drives. The simplest control strategy is the Zero d_axis current control (Constant Torque Operation) which is implemented in this model. The transient responses of torque, speed and 3-phase motor current are simulated.
