Abstract: Abstract: A mixed performance control problem of discrete-time linear
stochastic systems is discussed and investigated subject to H2
and passivity performances in this paper. Based on Itô modeling
approach, stochastic systems can be represented as deterministic
difference equation with multiplicative noise term. For
the stochastic systems, H2 minimization problem and passivity
constraint are simultaneously considered to achieve minimum
output energy and attenuation performance. Applying Lyapunov
theory, some sufficient conditions are derived into extended
Linear Matrix Inequality (LMI) form to apply convex optimization
algorithm. Moreover, a mixed H2/Passivity performance
controller can be designed such that asymptotical stability and
required performances of closed-loop system are guaranteed in
the mean square. Finally, some simulations are proposed to demonstrate
effectiveness and applicability of the proposed design
method.
