β¦ Synopsis
A new fast algorithm for linear quadratic (LQ) control optimization is derived using a partial state formulation and is exploited for the synthesis of long-range predictive controllers. The new algorithm requires O(Nn) computations for an nth-order plant and N-step prediction horizon and is about twice as cheap as existing fast algorithms. Systolic implementation on arrays of O(n) processors is also considered to get an O(N) processing time. Both fast algorithms and systolic implementation can be used to considerably speed up the control design task in adaptive predictive control schemes and thus increase the adaptation bandwidth.

In this paper two non-linear control laws for ships are derived by using a non-linear ship model which includes the hydrodynamic e ects due to time-varying speed and wave frequency. The non-linear ship model does not have the structural properties of symmetric inertia and positive damping at high sp
## Abstract In this paper, the adaptive variable structure control problem is presented for TakagiβSugeno (TβS) fuzzy timeβdelay systems with uncertainties and external disturbances. The fuzzy sliding surfaces for the TβS fuzzy timeβdelay system are proposed by using a Lyapunov function, and we des
The adaptive robust control design problem for low-dimensional systems is addressed in this paper. The proposed scheme consists of an orthotopic set membership identifier, a robust stabilizing controller and a pole placement controller. The identifier provides the minimum (volume-wise) orthotopic re
