In this paper the last two phenomena by concentrating on two kinds of channels were considered. These one is the channel that is digital and due to the finite word length the channel is digital and due to the finite word length effects only a finite number of bits can be transmitted over the channel at any transmission instant. The main issue in control (stabilization) of systems with such channels is that of quantization and we use the term quantized control systems (QCS) to denote this class of systems. The other is the channel which is a serial bus and only a subset of sensors and/or actuators can transmit their data over the channel at each transmission instant. In this case, the sensor/actuator data is transmitted in packets and typically the quantization effects are ignored in the analysis. The main issue in this class of systems is time scheduling of transmissions of various signals in the system and these systems are often referred to in the literature as networked control systems.
