Description
We offer Digital Control System usefull for control laboratory experiment. In the present unit a second order transfer function, simulated with operational amplifiers and passive components, has been chosen as the process to be controlled. This results in a well behaved and near perfect linear process which gives a highly predictable performance. The digital controller consists of a 8085 based microprocessor kit with analog-to-digital and digital-to-analog interface. Software supplied with the system resides in a 8K EPROM. This consists of P, PI and PID algorithms in which the three gains may be selected out of 16 levels each. Further, the user may write his own programs to implement additional algorithms and study their responses. Highlights of the equipment: >>Digital Controller implementation on mP-kit >>Simple Op-amp based analog plant >>CRO display of response >>Design and test new algorithms Experiment: >>Identification of the controlled process >>Study of sampling period variation >>Designing P, PI, PD and PID controllers >>Advanced algorithms implementation Features and Specifications: >>Second order simulated process (analog process) >>Built-in D/A and A/D circuits (8-bit) >>8085 based mP kit as digital controller with user software in 8K EPROM >>16-bit arithmetic for algorithmic calculations. >>Square wave test input (internal) >>16 built-in levels of P, I and D gains each. >>Complete flexibility for the user to develop own software >>IC regulated internal built-in power supplies >>Detailed literature and patch cords included >>Essential accessory - a CRO The experiment is complete in all respect.
