GROUP ASSIGNMENT-PROBLEM BASED LEARNING ASSIGNMENT
Problem Statement:
An Armature controlled dc motor is used to control the position of an antenna azimuth in which is shown in Figure 1. While the schematic diagram for this system is shown in Figure 2 and its corresponding parameters are highlighted in the Table 1.
Equation of motion which represents the system dynamics is derived by neglecting the dynamics of potentiometers. Thus, the relationship between the output voltage and the input angular displacement is given by;
[pic] (1.1)
The relationship between motor and load is given by;
[pic] (1.2)
In which the equivalent inertia, [pic] is derived from
[pic] (1.3)
Similarly the equivalent viscous damping, [pic] is
[pic] (1.4)
These quantities are substituted into the motor equation (i.e. eq. 1.2), yielding the transfer function of the motor from the armature voltage to the armature displacement. The gear ratio to arrive at the transfer function relating load displacement to armature voltage is;
[pic] (1.5)
From parameter values in Table 1, (i.e. choose your parameter configuration) design a controller consisting of P-I-D actions to improve the performance of the antenna system. The requirement is open which means that you should try to achieve as good as possible performance for transient, stability as well as signal tracking under unit step signal input.
To justify the reasonability of your results, simulate the system using MATLAB/SIMULINK.
