โœฆ Synopsis

The problem of transforming between continuoustime state variable feedback gains and equivalent discrete gains suitable for digital implementation is considered. The concepts of state and control equivalence yield two simple transformation rules, a pseudo-inverse method and an average gain method, respectively. As the sampling interval 3~0, these methods are contrasted with existing Taylor series based approaches. The new transformation rules are also studied numerically using a ship course-keeping example. Transformed optimal continuous gains are compared with optimal discrete gains over a wide range of sampling intervals.

A new decomposition-coordination approach is presented to design control laws for linear discrete-time systems with distributed lags. By a proper decomposition of the criterion, one obtains a control law with partial feedbacks and an open loop part in order to satisfy the optimality conditions. On-l

An indirect adaptive control for a discrete-time non-linear system that is fully input-output linearizable is developed. The unknown parameters of the system are identified by using a multi-output RLS algorithm. Based on the certainty equivalence principle, the estimated parameters are then utilized
