“…Among them, [9] proposed a linear matrix inequality based approach for H ∞ control design, leading to a solution for the case where K is of full order. One may also mention [10] which involves the Riccati equations and conditions on the observability and detectability to address a larger DAE class. Similarly, one limitation is related to the structure of the controller, which may increase with the model complexity.…”

This paper reveals a practical manner to deal with the control design of dynamical systems governed by input derivative index-2 first order differential algebraic equations. This class of dynamical model embeds a polynomial which results in a infinite gain in high frequencies. The idea is grounded on the construction of an adequate SISO controller structure to make possible the control design on a model presenting both rational and a first order polynomial parts. The design approach then leads to a controller in a rational form without any algebraic constrain, which can be implemented on a real-time target. Application for gust load control of a complex aeroservoelastic aircraft dynamical model, which naturally embeds an input derivative action, illustrates the approach, using an H∞-norm minimization performance objective.

In the modern welding technology of metal materials, the welding robot is a very important factor. And the welding wire feeding device is a very important part of the welding robot. The welding wire feed systems stabilization and reliability is essential for the welding quality. The resistance is caused by the draw of welding wire and other factors, which is highly nonlinear and stochastic. The wire feed rate and welding quality will be severely affected by the resistance. This paper investigates the method controlling the system according to the observations of the resistance, speed and other factors. There are the complex environmental factors in the welding process, such as the strong magnetic field and high current field, which are random. So the robust control algorithm based on the state space model is designed to keep the welding wire feed speed stable under disturbances. The robust control method can improve the speed of response and eliminate the effect of wire feed resistance to the wire feed speed. Even when disturbed, the system can quickly reach a stable wire feed speed.
