supplies, DPMs, Computer Interface, Analog PID controller with central slot to hold various replaceable experiment panels.
Connection through sturdy 4mm Banana sockets & Patch cords.
Students workbook & Instructor’s Guide provided with each unit.
Process Simulator Panel / CE1
• Functional blocks for Lag (3No), Integrator (3No), Transport Lag (1No), Summer (2No), Gain (1No),
Inverter (2No) for constructing simulated Type 0,1,2,3 & 1 st,2 nd,3 rd Order processes to work under PID.
• Experiments with Lead / Lag / Lead - Lag compensators to control behaviour of matching processes using
above function blocks.
• Open loop & close loop response of processes under different P, PI, PID - Analog or Digital controllers.
• Auto Tuning explained using ziegler Nicolas method I & II.
• Fast (10mS) & slow (1sec) mode selection for all processes to observe response on either CRO or on PC
using data acquisition interface.
• Drawing Bode plot & Nyquist plots, transfer function determination.
• Optional experiments with advance process control scheme viz; Ratio, Cascade, feed forward.
• Level shifters (2No) ±9V to 0-2.5V & 0-2.5V to ±9V to match voltage levels of PC (2.5V) and opamps
(+9V).
