The paper presents common cascade control architecture where specific kind of redundancy could be considered. There are different approaches how to increase the reliability of networked control systems. Common approach uses redundant components in control system i.e. passive or active redundancy. We deal with quasi-redundant subsystems (shared redundancy) which could be very useful when critica...

The matrix calculus is widely applied in various branches of mathematics and control system engineering. In this paper properties of real matrices with nonnegative elements are studied. The classical Collatz theorem is unique and immediately applicable to estimating the spectral radius of nonnegative irreducible matrices. The coherence property is identified. Then the Perron–Frobenius theorem a...

In this paper, a unified approach for control systems education will be presented. This approach is a friendly software and hardware platform that provides students with the necessary tools for gathering data for system identification, designing controllers, simulating the closed-loop system, and implementing the controller on real-time hardware. The proposed approach has been used in introduct...
