TERM PROJECT

The project involves control design and implementation for a suspended object. A moving
cart is attached to a motor to move a simple pendulum (see Fig. 1). The relevant system
parameters are given below. The system has three sensors to measure the two angles and
vertical position of the suspended object.

The objective is to stop the suspended object as fast as possible by moving the hoisting cart
or/and the hoisting cable.

Design Criteria: The cart can move in two directions from the initial position. The cable can
be also lift or lower the moving mass. You should come up with your own design
specifications (e.g., settling time, overshoot, rise time etc) to meet the objective. Keep in
mind that the real system contains nonlinear effects.
The competition: The teams will present their designs and they are given three trials to test
their controllers on a real crane, see Fig(1). The team with the smallest average time for a
successful operation will win the competition. Twenty percent of the project grade will
depend on the normalized scores.
The project will be carried out in two phases. The following is an outline of the steps for the
first phase.

â€¢ Develop a mathematical model for the system.
â€¢ Develop a Simulink model to carry out simulations and design the controllers.
â€¢ Design some simple control systems and simulate the response
â€¢ A progress report should be submitted by Wednesday, may. 27, 2012.

The second phase will involve designing and testing various controllers. A formal project

report is to be submitted by may 29, 2012. The teams will present their designs on June 3, 2012.

System Parameters:

Maximum speed: 0.3m/s
Maximum acceleration: 0.9 m/sÂ² Cord length: 40 cm
Suspended mass: 0.5 kg
Sensor gains are to be taken as unity.
