ASSIGNMENT - PID CONTROLLER
A plant is controlled as shown in the block diagram below:
The plant dynamics are represented by:
G(s) = 1/(s+0.5)(s+0.2)
Part 1: Theoretical compensating function
Determine a compensating function Gc(s) such that one of the poles is eliminated. Provide all calculations in detail with explanation.
Part 2: Computer simulation
Using the Matlab Control System Toolbox, provide the following items, providing documentation on your methods and commenting on your results.
1. Construct and document a model of the plant.
2. Construct and document the functions R(s) and C(s) for a step response and an impulse ?response on the input R(s).
3. Provide a Bode Plot.
4. Use an appropriate Matlab tool to determine the stability of the control system.
Part 3: Practical implementation study
Describe in one paragraph each, two possible methods of real-time practical implementation of a control system. Choose from non-programmable control systems hardware, programmable logic controller or robotics. Cite a practical commercial example of each.
