A Student-Oriented Control Laboratory Using Program CCAbstractControl course is a classic and yet a difficult course in engineering education. Its traditionallaboratory component is to use analog device to simulate the control system, which lacks theemphasis on the soft side of intelligent control design skills. In order to well prepare ourengineering students for the challenges presented by advanced technologies in the 21st century, astudent-oriented control laboratory has been developed in our college for a senior control course.The laboratory use Windows XP based software, Program CC, which provides a powerful toolfor efficiently and effectively developing sophisticated control systems in a wide range ofapplications. In the laboratory, a sequence of eight application projects was elaborated. Thetopics of lab projects include the following designs: ship control systems, aircraft controlsystems, satellite-tracking antenna control systems, DC motor control systems, automotivepower train control systems, PID controllers, etc. With these hands-on projects, students not onlylearned how to design, analyze and synthesize a control application system, but also reinforcedtheir understanding of theoretical and abstract subjects in control theory. Test results and studentsemester surveys demonstrate that our newly developed laboratory made contributions inenhancing student intelligent control design skills on the soft side, which is highly demanded fora 21st century and future engineer.As an example, one of the eight hands-on laboratory projects is presented on the next pageLaboratory Assignment 1Consider the 270-ft U.S. Coast Guard cutter Tampa (902) shown below. Parameter identificationbased on sea-trials data (Trankle, 1987) was used to estimate the hydrodynamic coefficients inthe equations of motion. The result is that the response of the heading angle of the ship towind change w can be described by the following transfer functions ( s) 0.0184(s 0.0068) G (s) , (s) s(s 0.2674)(s 0.0063) ( s) 0.0000064 Gw (s) , w(s) s(s 0.2674)(s 0.0063)where heading angle, rad, r reference heading angle, rad r yaw rate, rad/sec rudder angle. Rad w wind speed, m/sec.Using Program CC:(1) To design a controller to regulate the heading angle by using and the measurementprovided by a yaw-rate gyroscope. The settling time of to a step change in r is specified tobe less than 50 sec, and for a 5 change in heading, the maximum allowable rudder angledeflection is specified to be less than 10(2) To check the response of the closed-loop system you designed in part (1) to wind gustdisturbance of 10 m/sec. If the steady-state value of the heading due to this wind gust is morethan 0.5 , modify your design so that it meets this specification as well.
