This correspondence presents a new approach that utilizes evolutionary computation and
proportional-integral differential (PID) control to a multi-input multioutput (MIMO) nonlinear …

In this paper, a helicopter-like twin rotor multi-input multi-output system (TRMS) is decoupled
and is fuzzy Takagi–Sugeno modeled with the complex nonlinear functions simplified as the …

This investigation presents the mathematical modelling of an experimental aerodynamic test
rig, a twin-rotor multiple input-multiple output (MIMO) system (TRMS). The system is …

Twin rotor systems in many ways resemble helicopters and they are multiple-input multiple-
output (MIMO) systems, highly nonlinear, and there is significant cross-coupling between …

Ambiguity is always present in any realistic process. Imprecisely defined classes play an
important role in human thinking. The ambiguity may arise from the interpretation of the data …

Conditional integration is a technique used to improve the transient performance of
controllers with integral action. This paper proposes a novel modification of this technique …

This paper addresses the attitude control problem for a twin rotor unmanned helicopter
driven by DC motors. The control objective is to have the helicopter attitude, ie, pitch and …

This paper analizes a linear and a nonlinear PID control algorithms for a twin rotor MIMO
system (TRMS), which is characterized by its nonlinearity, two degrees of freedom and cross …

This paper considers designing an adaptive fuzzy controller to position the yaw and pitch
angles of a twin rotor MIMO system (TRMS) in two degrees of freedom. The goal of the …

This paper presents the development of a hybrid fuzzy-PID-based control approach for an
experimental aerodynamic test rig-a twin rotor multi-input-multi-output system (TRMS). The …
