Linear System Simulator, LSS-01
We are indulged in manufacturing, exporting and supplying LINEAR SYSTEM SIMULATOR to our customers in Roorkee, Uttarakhand, India.
The most important performance aspect of a practical system is its response to known input. A large part of the analysis of such systems is therefore devoted to time domain studies. The set-up offered is a variable configuration simulated system designed for time domain studies of both open loop and closed loop systems. Selection at block diagram level eliminates the need to bother about the details of electronic circuitry and its assembly. Thus time and efforts could be directed towards understanding and experimenting with the basic aspects of linear control systems.
Schematic diagram of the simulator shown includes transfer functions of the form 1/s and 1/(sT+1), a calibrated variable gain K and an error detector. These could be combined to form a variety of system configurations. The unity gain uncommitted amplifier can be used to ensure negative feedback. The time constants have been selected such that the system response may be observed conveniently on a CRO. This avoids the need to use an expensive and delicate X-Y recorder for the experiment.
