“…Similar controller has been applied to control an unmanned X-Cell helicopter model, 17 where Mamdani-type fuzzy controllers generate the set-points for the PID controllers for z (vertical)-position, and roll, pitch and yaw angles. Another example of this approach has been presented in Pratumsuwan and Thongchaisuratkrul, 18 where a proportional hydraulic system has been controlled using fuzzy pre-compensator. The fuzzy pre-compensator uses the command input and the plant output to generate a pre-compensated command signal.…”

This article addresses the input tracking control problem of a highly nonlinear flexible system namely a twin-rotor multi-input multi-output system in the vertical plane motion. The twin-rotor multi-input multi-output system can be considered as an aerodynamic experimental model, representing the control challenges of complex air vehicles. A hybrid control scheme comprising a fuzzy proportional–derivative-like control and a conventional integrator is developed by adding the outputs of both control actions. To satisfy the tracking characteristics of the manoeuvring system, an efficient combination of the control actions is developed using a smooth nonlinear activation function which continuously regulates contribution of the integral term in the controller output. The effect of the activation function greatly reduces overshoots when the system is exposed to abrupt changes during its manoeuvre. The control system performance is tested in simulations and experimentally in real-time situations. Robustness and stability of the controller are also investigated. The obtained results prove the efficiency of the proposed scheme in terms of time-domain performance specifications of the system.
