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...

The design of multivariable ripple-free deadbeat controllers is a complex task. One approach which has shown promise for solving multivariable ripple-free deadbeat control (MRFDC) problems is the use of Diophantine equation parameters. The problem of solving robust multivariable ripple free deadbeat with time delays has not been solved. This paper proposes a hybrid two degree of freedom control...
