SHIPSIM/OPTSIM: SIMULATION PROGRAM FOR STATIONARY LINEAR OPTIMAL STOCHASTIC CONTROL SYSTEMS

The SHIPSIM/OPTSIM computer program for the simulation of stationary, linear optimal stochastic control systems is presented. This program consists of two separate entities: SHIPSIM is a general continuous system simulation program designed to provide a versatile simulation capability with simple user input. This program can be used for any continuous systems simulation problem which can be defined in the three user-supplied subroutines; and OPTSIM is a group of subroutines which are run under SHIPSIM for the simulation of the response of stationary, linear optimal stochastic control systems to initial condition errors and specific user-supplied process disturbances while subject to measurement white noise. These two program groups are described; User's Documentation, Programmer's Documentation, and listings are included as appendices. A simulation of an optimal stochastic path controller for a tanker operating in shallow water is presented as an example. The programs are written in FORTRAN IV and with the exception of the plotting portion of SHIPSIM, they are essentially independent of the Michigan Terminal System (MTS). (Author)
