✦ Synopsis

To counter the problem of lower controlling precision of conventional fuzzy control algorithm based on look-up-table, this paper puts forward an improved fuzzy control algorithm that has high controlling precision. Firstly, the paper analyses the reason for causing lower controlling precision of the look-up-table algorithm, then submits an improved algorithm to solve the problems and gives its design method. Finally, given the simulation results of the improved fuzzy control algorithm, we compare them with the simulation results of the look-up-table algorithm and hybrid fuzzy control method. The improved algorithm keeps the advantages of look-up-table algorithm and has higher controlling precision during the steady state. It keeps the simple structure of the look-up-table controller and leads to a little higher computational complexity. The improved algorithm is simple and easily implemented.
