In the paper, there is presented a MATLAB Toolbox that allows simulation and parameter tuning of closed-loop systems with fractional-variable-order digital PID (FVOPID) controllers. The proposed ...

Under the simulation of MATLAB, the double closed-loop system of current type 1 and speed type 2 obtained by the V-M system meets the requirements, and the results are successfully verified.

Edexcel The function of structural components of programs - Edexcel Condition-controlled iteration Programs are designed and implemented using common building blocks, known as programming constructs.
