We propose a method of interpolating linear time-invariant controllers with observer state feedback structure in order to generate a continuously-varying family of controllers that stabilizes a family of linear plants. Gain scheduling is a motivation for this work, and the interpolation method yields guidelines for the design of gain scheduled controllers. The scheduling method is illustrated w...

Abstract – The modeling and control of 3 Degrees-of-Freedom (DOF) four-rotor rotorcraft is presented in this paper. Optimal control (LQR), LQR with gain scheduling, feedback linearization and sliding-mode control are simulated and tested on an experimental rig. The performance of the individual controllers are compared and discussed. Our simulation showed Sliding Mode Control (SMC) returned the...

Parametric linear constant and gain-scheduled control systems design are studied for a class of linear parameter varying (LPV) systems and piecewise linear (PL) systems based on stabilization via convexity restrictions. Specifically, the maximum row sum (matrix) norm is utilized to obtain a computationally attractive state space method for the scheduling of simple linear controllers under incom...

University of Strathclyde Abstract This paper investigates the application of the gain-scheduling approach to flight control tasks where the conditions required by conventional techniques need not be satisfied. The conditions required by conventional techniques are progressively relaxed and the design of gain-scheduled controllers under a range of conditions is addressed. In particular, the pap...

This paper is an extension of the previous work realized by the authors. Here a discrete-time multiple input multiple output (MIMO) linear parameter-varying (LPV) controller is designed, a polynomial approximation for disturbances with harmonically related frequencies to reduce the number of gain-scheduling parameters is used and the controller is validated experimentally for the rejection of t...

There are many control methods of wind power generator set, and various control technology has successful applied cases,however, with the content augment of set, we need to improve dynamic stability. The routine traditional control technology (for example PID control) can’t satisfy the requirements now. Aiming at the particularity of wind power generator set, the paper puts forward a new gain s...

A new approach to gain scheduling linear dynamic controllers is illustrated on a pitch-axis autopilot design problem. In this application the linear controllers are designed at distinct operating conditions by H-Innnity methods. The gain scheduling procedure uses particular features of both the linear dynamic controllers and the controller connguration to remove so-called hidden coupling terms ...

The aim of this paper is to discuss the use of gain scheduling to improve the performance of classical AQM controllers. We show that by using gain scheduling it is possible to synthesize controllers able to better cope with unwanted variations of the network operating regime; for example variations of the round-trip time, the load or the buffer capacities. Simulations are provided to compare th...

We present a control design method for nonlinear partial differential equations (PDEs) based on a combination of gain scheduling and backstepping theory for linear PDEs. A benchmark first-order hyperbolic system with an in-domain nonlinearity is considered first. For this system a nonlinear feedback law, based on gain scheduling, is derived explicitly, and a proof of local exponential stability...
