Basic Control System Trainer is a very versatile and useful trainer kit for the control laboratory for all engineering, polytechnic and vocational courses. It provides with in depth knowledge of the basics of control systems like open loop, closed loop, Ist, IInd and IIIrd order systems active and passive, Type 0, 1, and 2 control systems. Practical and Theoretical concepts can be verified for all types of control systems. The unit is housed in an elegantly designed metal cabinet with a well spread circuit layout on the front panel. A comprehensive Instruction Manual complete with Theory and Operation details is provided. These are some of the salient features of the Basic Control System Trainer.
