Design and analysis of linear sampled-data control systems using digital simulation techniques

The problem of discrete compensator design for acceptable transient response in linear stationary plants modeled in state-variable form is considered in this research. A digital computer algorithm is programmed in FORTRAN for calculation of the feedforward compensator transfer function coefficients. The generalized method for realization of the compensator is demonstrated. System performance with no compensation, classical phase-lead compensation, and discrete compensation is exemplified via a CSMP simulation. An investigation of the effect of saturation nonlinearity in the plant with respect to the discrete compensator design is included.
