Nonlinear control system analysis and design with Maple

For the analysis and design of nonlinear control systems non-numerical methods are available. The required analytical computations are mostly too tedious to be done error free in a reasonable time by hand, so the use of symbolic computation programs can be of advantage. To show that the symbolic computation program Maple can be used to solve simple but representative analysis and design problems, four `benchmark' cases are used. Problems encountered are discussed. Recommendations for the enhancement of Maple are give
