This paper presents the design of a Multi-Input Multi-Output (MIMO) PID controller for twin-rotor MIMO system. A multivariable control system consisting two loops is designed non-linear with inputs and outputs. The controllers have been tested on simulated model different possibilities real-time results were taken. efficiently controls does not suffer from any process interactions. indicate tha...

We consider the problem of studying sensitivity ellipsoidal frequency estimates quality multivariable dynamic systems to parameter variations. To solve problem, we use apparatus functions extreme elements singular value decomposition real-valued transfer matrices. The joint usage with method state space allowed us construct models sensitivity. On basis obtained models, for state, output and err...

We define a new type of multivariable multiple hypergeometric functions in this paper, which is inspired by Exton's given [13]. Then, for these functions, we obtain some certain linear generating functions. After that, derive variety classes multilinear and multilateral family the In addition, employing Erkus-Srivastava polynomials (see [11]) fourth Horn [13]), have also provided its conclusions.
