Run a string as a command within a Bash script

I have a Bash script that builds a string to run as a command

Script:

#! /bin/bash

matchdir="/home/joao/robocup/runner_workdir/matches/testmatch/"

teamAComm="`pwd`/a.sh"
teamBComm="`pwd`/b.sh"
include="`pwd`/server_official.conf"
serverbin='/usr/local/bin/rcssserver'

cd $matchdir
illcommando="$serverbin include='$include' server::team_l_start = '${teamAComm}' server::team_r_start = '${teamBComm}' CSVSaver::save='true' CSVSaver::filename = 'out.csv'"

echo "running: $illcommando"
# $illcommando > server-output.log 2> server-error.log
$illcommando

which does not seem to supply the arguments correctly to the $serverbin.

Script output:

running: /usr/local/bin/rcssserver include='/home/joao/robocup/runner_workdir/server_official.conf' server::team_l_start = '/home/joao/robocup/runner_workdir/a.sh' server::team_r_start = '/home/joao/robocup/runner_workdir/b.sh' CSVSaver::save='true' CSVSaver::filename = 'out.csv'

don't put your commands in variables, just run it

matchdir="/home/joao/robocup/runner_workdir/matches/testmatch/"
PWD=$(pwd)
teamAComm="$PWD/a.sh"
teamBComm="$PWD/b.sh"
include="$PWD/server_official.conf"
serverbin='/usr/local/bin/rcssserver'    
cd $matchdir
$serverbin include=$include server::team_l_start = ${teamAComm} server::team_r_start=${teamBComm} CSVSaver::save='true' CSVSaver::filename = 'out.csv'
