In control system there are different types of controller. Study of two-position mode as ON/OFF controller and continuous controller modes as PID controller is a very important part of control engineering. To have a basic idea and practical hands on controllers our PID Trainer has been designed to be used by student to investigate the fundamental principles of PID by applying different signals to it. With PID controller trainer student can study two position mode as ON/OFF controller and continuous controller modes as P-control mode, I-control mode, D control mode, PI-control mode, PD - control mode and PID control mode. This modes of controller can be performed individually and also with different combinations in open loop and close loop system. With this trainer user can easily understand the difference between the different modes of controllers used.

Digital Control System

Code:EET2901

Digital Controller implementation on mP - kit Simple Op-amp based analog plant CRO display of response Design and test new algorithms Introduction Digital control of industrial processes has become very important today because of the advantages it offers and the increased availability of inexpensive computing power of microprocessors. The principal advantages include fixed hardware with complete software flexibility and the feasibility of implementing integration and differentiation on extremely slow varying signals. On the other hand digital controllers have some drawbacks also such as errors due to the processes of sampling and reconstruction, computational errors caused by finite wordlength, truncation, register overflow, as well as the de-stabilisation effects of sampling. A clear understanding of all these aspects is of great value to a student of control engineering. 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 and enables the student to concentrate on the design and evaluation of the controller. The digital controller consists of a 8085 based microprocessor kit with analog-to-digital and digital-to-analog interface. The dynamic ranges of the variables in the whole system and that of the built-in square wave test input signal are made compatible. The step response may be displayed and studied using an external measuring CRO. Software supplied with the system resides in a 8K EPROM. This consists of P, P-I and P-I-D algorithms in which the three gains may be selected out of 16 levels each. All arithmetic calculations are performed in 16-bits and are also available to the user as subroutines. Detailed information and listing of the software is included in the literature, besides suggestions and procedures for conducting experiments. Also included are typical results of some experiments with their theoretical descriptions. Further, the user may write his own programs to implement additional algorithms and study their responses.

Experiments

  • Identification of the controlled process
  • Study of sampling period variation
  • Designing P, PI, PD and PID controllers
  • Advanced algorithms implementation

A.C. Servomotor Study

Code:EET2906

Two phase a.c. servomotor is one of the very important electromechanical actuators having applications in the area of control systems. The studyof its operating principle and features form a part of the first course on automatic control systems inelectrical engineering curriculum. It's smallsize, low inertia and almost noise and frictionless operation makes the a.c. servomotor particularly attractive in aircraft and spacecraft applications. The characteristics of an a.c. motor is usually non-linear. To simplify the analysis a linearized model is developed. The experimental work revolves around determination of the parameters of the motor and thus its transfer function. Important subsystems of the unit includes, (a) an integrated speed sensor with 4-digit display in r.p.m. (b) an electrical loading system to compute torque (c) a time-constant measurement circuit with 3-digit display in milli seconds (d) a three step a.c. source with built-in r.m.s. voltmeter, and (e) a digital voltmeter on the panel for load measurement The unit has been designed such that expensive equipment like storage CRO is not needed. Also the hassle of direct torque measurement usingspring balance etc. is avoided by linearization of the motor characteristics analytically.
