In this work we present some of our successes in combining MATLAB®-based simulation methods with Telecommunications Instructional Modeling (Emona-TIMSTM) experimental methods to enhance student learning in a senior-level communications systems laboratory. While faculty have discussed the relative merits of simulation versus real experimentation in recent years, we find that combining these approaches...
This paper presents a successful graphical technique for finding all discrete-time proportional integral derivative (PID) controllers that satisfy a robust stability constraint for heading control of a 2 meter autonomous sailing vessel. This problem is solved by finding all achievable discrete time PID controllers that simultaneously stabilize the closed-loop characteristic polynomial and satisfy...
We present an alternative method to teach amplitude and phase distortion concepts using time domain methods. Typically, these concepts are taught using relatively expensive network analyzers. Here we show how a transcendental waveform, generated using relatively inexpensive waveform generators, and observed using standard lab oscilloscopes, can be used to illustrate amplitude and phase distortion,...
This paper presents some of the successful design methodologies used to predict the robustness of a heading controller for a 2 meter autonomous sailing vessel. A graphical technique is introduced to estimate the discrete-time proportional integral derivative (PID) controller coefficients to satisfy H-infinity complementary sensitivity constraints for vessel control. We show that this problem can be...
