Controllability of nonlinear control systems
1986 25th IEEE Conference on Decision and Control, 1986Controllability properties of analytic affine control systems ? with an arbitrary number of controls and no a priori bounds are studied, without any restriction on the dimension of the Lie algebra T' generated by the input vector fields. Sufficient conditions for local controllability at a point are presented, involving the Lie brackets at that point ...

Nonlinear control and controller tuning
Proceedings of the 35th SICE Annual Conference. International Session Papers, 2005The objectives of the paper are to discuss aspects of controller design, or more specifically controller tuning, for a SISO plant which may be nonlinear. The paper therefore first considers nonlinear effects and some approaches to the analysis of nonlinear systems. The autotuning approach for PH) controller tuning is then discussed first for linear and

Every physical system in our real life has nonlinearities and very little can be done to overcome them. Many practical systems are sufficiently nonlinear so that important features of their performance may be completely overlooked if they are analysed and designed through linear techniques. In HDD servo systems, major nonlinearities are frictions, high-

Exact linear models are obtained using the technique known as input–output feedback linearization, that is applied to a bilinear finite-dimensional state-space approximation of the dynamics of a distributed collector solar field. A control Lyapunov function is then used to jointly design the adaptation law for the uncertain parameter that measures the ...

The paper introduces the concept of nonlinear integral controls. It is shown that by using a nonlinear integral transformation one may design stabilizing controls by resorting to the integration of the nonlinearities, a procedure at the core of this approach, as opposed to differentiation of the nonlinearities which characterizes most methods developed,

The previous chapter has been devoted to solving point and posture tracking problems by state feedback linearization for the five generic types of wheeled mobile robots. However, as it has been already mentioned, feedback linearization through regular controllers has serious limitations for control of mobile robots.
