Implementation of Online Control Customization within the Open Control Platform

The concluding chapter of this part of the book discusses several flight control implementation examples that integrate Matlab/Simulink within the open control platform (OCP) framework (described in Chapters 4 and 5). A public domain version of an F-16 aircraft model, available as a Simulink block with OCP distribution 1.0, is used for illustration. The first example is a linear quadratic regulator (LQR). The LQR controller was written as a Matlab ”mex” function in C. A Matlab process behaves as an ”LQR server.” The ”LQR client” is an OCP component in a Simulink block; when Simulink invokes the block, the client sends the simulated aircraft’s state vector to the LQR server. The server generates the control signal and returns it to the client, which then writes it to the output port of the Simulink block. In this example, Simulink drives the simulation, which is therefore completely synchronous. The second example demonstrates the use of Matlab/Simulink as a visualization package within OCP. A linear parameter varying (LPV) controller was designed, initially in Simulink. Both this Graduate Assistant, [email protected] †Professor, [email protected]
